ISABELLE, who works for Solar Airways as a Ground Service Agent, has posted a notice looking for a doll. BELLE regards this doll as a lucky charm that has helped bring her parents together. She hopes it too will bring her to her Prince Charming in the near future. Senior First Officer SAMUEL has found the doll, and he contacts BELLE under a fake name of ‘MR. Y’. Passenger ZOE is not feeling well, but due to the poor weather conditions, the plane cannot make its landing at the scheduled time. SAM, as one of the pilots on the plane, gives ZOE some words of comfort. SAM has lost the doll but ZOE later gets it by chance. SAM’s mother CAMMY has left SAM and his father PHILIP since many years ago. SAM has always wanted to fly her home so that the whole family can be together again. First Officer VINCENT is a good friend of SAM. His good looks and natural charisma make him a lady-killer……

Due to some misunderstanding, SAM and BELLE feel that they are cheated by each other, and their relationship has finally broken down. BELLE later meets VINCENT. They get attracted by each other and promptly fall in love. One year later, VINCENT introduces BELLE to SAM. SAM is shocked to see BELLE again while BELLE treats him like a stranger. ZOE can never forget how the airport staff looked after her when she was sick. She is grateful to them all and decides to join the airport team. PHILIP, as the Chief Chef of Solar Airways, needs to develop new dishes. He then goes overseas to get some inspirations, where he meets CAMMY again. The couple, after being separated for so long, realize their true feelings for each other and decide to get back together again. VINCENT has bought BELLE a lot of dolls, in a vain attempt to get her what she wants……

PHILIP and CAMMY have not yet told SAM and ISAAC about their true relationship – SAM and ISAAC are not aware that they are actually brothers. The lie began when CAMMY got divorced all those years ago. CAMMY found that she was pregnant just after her separation with PHILIP and she alone had to bring up ISAAC. For the sake of convenience, she has long claimed that ISAAC is her brother while ISAAC has always believed that CAMMY is his elder sister. SAM and ISAAC have different personalities and they do not get on well. SAM and BELLE are invited to feature in the promotional video for Solar Airways. SAM looks a bit embarrassed during the filming. VINCENT has changed a lot since he met BELLE. He is now ready for a serious relationship and he knows for sure that BELLE is the one for him. ZOE introduces herself to SAM and returns the doll to him. ZOE tells him that the doll has brought her good luck, so SAM decides to let her keep it……

SAM finally gets aware of the true relationship between himself and ISAAC. PHILIP and CAMMY are leaving for their honeymoon. Before they go, they have appointed SAM to reveal the truth to ISAAC. ISAAC does not look up to SAM. He thinks the job of a pilot is not as difficult as it seems and decides to apply for the post of Cadet Pilot. ISAAC happens to meet DONALD MAN, the son of tycoon CHEONG, and another young lad CHRIS TSE. He has a little misunderstanding with them at first but they all become good friends later on. ZITA goes to CHEONG’s company to claim for compensation, where he meets DONALD. DONALD immediately has a crush on ZITA. ZITA learns from her mother TINA that Solar Airways is recruiting Cadets. She then decides to submit her application. SAM explains to ISAAC that the job of a pilot is not as easy as he thinks and that he needs to give serious consideration to all factors before he submits his application……

ISAAC has joined a course to learn how to control a light plane. There he meets ZOE and her cousin PAUL. To seek more opportunities to approach ZITA, DONALD decides to apply for the post of Cadet. CHRIS thinks it would be nice to be a pilot, so he submits his application too. PAUL has dreamed of being a pilot. He applied many times for the position of Cadet but has never been selected. He is not going to give up, though. SAM, VINCENT and another First Officer TONY are to interview the candidates. VINCENT asks SAM about his relationship with BELLE. ZITA is going to attend the interview and DONALD arranges to drive her to the airport. Candidate ROY has a problem with his car and is in a hurry to get a taxi so that he can attend the interview on time. DONALD, who is on his way to the airport, does not mind giving ROY a lift. SAM has a prejudice against ISAAC……

BELLE now believes that SAM is the one chosen for her. PHILIP and CAMMY dare not tell ISAAC the truth about his identity, which annoys SAM. DONALD, ISAAC, CHRIS, ROY and ZITA are all selected as Cadets. PAUL is the only one who fails the screening test. ZOE happens to discover that ISAAC is SAM’s younger brother. She then sends ISAAC a greeting card. BELLE asks SAM out because she wants to figure out what actually happened in Rome. ZITA was brought up by TINA and has no clue about who is her father. TINA tells her that her father died many years ago, but she doubts it. TAYLOR, a friend of TINA who lives in Japan, looks after ZITA in every way possible, which makes ZITA believe that TAYLOR might be her father. DONALD and CHRIS go on a trip to Japan before the training program starts. ZITA joins them so that she can pay TAYLOR a visit. ISAAC is astonished to discover the truth. He is upset and finds it hard to face his family……

DONALD tries his best to look after ZITA when they are in Japan. ZITA, however, only treats him as a friend. ZITA does not have a clue about Japanese. Luckily, ISAAC, who is well versed in a number of languages, stays with her and helps her out as much as he can by translating for her. ZOE invites DONALD and his mates to stay in her brother’s house. ZOE, PAUL, DONALD and others have therefore become good friends. SAM is shocked to hear that ISAAC has disappeared. As he finds that ISAAC is in Japan, he immediately arranges to fly to Japan to see his brother. For this reason, he fails to meet BELLE. ZITA gets aware of TAYLOR’s whereabouts, and realizes that she has met him once in a temple. When confronting TAYLOR, ZITA feels a little shy and does not dare to ask about their relationship. To help ZITA out, ISAAC has raised a number of questions about TAYLOR’s past, including his love life……

DONALD is happy to get an amulet from ZITA, but as he finds that every friend of hers has also got one, he gets so disappointed. ZITA goes to visit TAYLOR, who later invites her to take a flight in a light plane. ISSAC and SAM have a nice talk with each other, sharing all those fond memories of their childhood. VINCENT proposes to BELLE, but BELLE hesitates. BELLE has got a message from SAM saying that he has something very urgent to deal with. She then understands why SAM did not come to meet her. VINCENT is invited to SAM’s family reunion party. In SAM’s house, VINCENT happens to read the email sent to SAM by BELLE. He gets so angry as he knows that BELLE still misses SAM. BELLE confides in RUBY and says she will not accept VINCENT’s proposal until she is quite clear what she wants. DONALD holds a party at his home and he invites ISAAC and all other Cadets to come. He takes it as a great opportunity to get closer to ZITA……

BELLE finally accepts VINCNET’s proposal and VINCENT is over the moon. SAM congratulates VINCENT, in an attempt to conceal his disappointment. PAUL has applied for a transfer to ZOE’s department so that he can work with her. ISAAC is employed by Solar Airways as a Cadet and he is on his way to sign the contract. At the airport he meets ZOE and a young lad who is trying to take his own life. ISAAC and ZOE have a talk with the lad, trying to stop the lad from killing himself. For this reason, ISAAC cannot attend the contract signing ceremony on time. SAM blames ISAAC for being late. ZOE explains to SAM what has happened, and SAM decides to give ISAAC a second chance. On his first day of work, PAUL meets a drunken passenger. For safety reasons, PAUL does not allow that drunken passenger to get on the plane. RUBY finds that ZOE has got the doll. She then tells ZOE the story behind……

ISAAC and DONALD have arrived in Australia, and the six-month training program is about to start. TONY offers a brief orientation tour to the Cadets. ISAAC thinks that he deserves special treatment because of his close relationship with SAM. SAM, however, insists that he has to be fair to everyone and in fact he puts even higher demands on ISAAC. VINCENT’s parents have emigrated to Australia, and for this reason, VINCENT wants his wedding to be there. VINCENT’s younger sister CHARLIE does not seem friendly on her first encounter with BELLE. VINCENT invites SAM to his wedding, which makes SAM a little upset. ZOE meets her former teacher at the airport. When she hears about her teacher’s love story, she comes to realize even little misunderstanding can ruin a relationship. Looking back on what she has done, she feels so guilty towards SAM and BELLE and really wants to do something for them……

Just after BELLE’s wedding, SAM finds that there has been some misunderstanding between himself and BELLE. However, he has realized it too late. VINCENT meets MIMI again, from whom he knows that there is some misunderstanding between BELLE and SAM, which made them end their relationship. VINCENT thinks it is all his fault and regrets what he has done. After a long long struggle with his conscience, VINCENT decides to reveal the truth to BELLE so that she can make a choice again. BELLE has lost SAM and she does not want to hurt VINCENT. She has finally chosen VINCENT. ZOE has been on holiday for quite some time, leaving much of her work undone. RUBY needs ZOE to finish everything the day she returns to work. PAUL wants to help ZOE and asks RUBY to give her some more time. PAUL gives RUBY a lift and RUBY breaks out in a rash after sitting in his car for only a short time. RUBY is therefore absent from work……

ZOE knows that PAUL falls for RUBY. She then tries her best to create opportunities for PAUL. ZOE speaks highly of PAUL, trying to convince RUBY that he is really a nice bloke. She even helps PAUL to move into RUBY’s house. ZOE shows care and concern for SAM, and SAM is very grateful indeed. ISAAC has got from ZITA some hints on how to study more effectively. He has obtained a very good result in the examination but SAM suspects him of cheating. SAM asks ISAAC to re-take the examination so as to prove his innocence. Again, ISAAC performs well in the exam. SAM needs to return to Hong Kong to report on the Cadets’ progress. The night before he leaves Australia, he packs his bags and finds a greeting card from ISAAC. He then knows he has misunderstood his younger brother. To spend more time together with PHILIP, CAMMY decides to join the administration team of Solar Airways……

For DONALD, ISAAC and all other Cadets, this is the first time they have been able to operate a plane. They are all very excited. SAM heads back to Australia to carry on with the training program. CHEONG’s personal assistant TAK persuades DONALD to go back to CHEONG’s company but DONALD refuses straight away. ZITA overhears the conversation between DONALD and CHRIS, and is shocked to discover that DONALD has joined the Cadet Pilot Program for her sake. ISAAC has made a fatal mistake during a flight training session. He is not allowed to carry on with any flying training until two weeks later. ZITA suggests that DONALD should abandon his plan to become a pilot so that his time will not be wasted. After serious self-examination, DONALD is absolutely sure that he loves flying and it has been his dream to be a successful pilot. SAM goes to visit VINCENT’s parents……

TONY and SAM hold a celebration party for the Cadets. ZOE discovers that the lovesick TAT keeps on wandering around the airport all day long. A pregnant woman at the airport is about to give birth to her baby, so ZOE and BELLE have both come to offer help. The woman gives birth to a baby girl. ZOE and BELLE ask if they can be the godmothers of the baby. All the Cadets are required to learn to fly different types of aeroplanes. The final examination is approaching. To pass the exam, they will first of all have to work in pairs or groups to work out a route and according to which they will then have to fly a plane from a location to another. DONALD, ISAAC and ZITA are placed in the same group. They have accidentally flied into the clouds and worse than that, their plane undergoes a catastrophic malfunction – they are really in great danger! But the power of a good team spirit has helped them tackle all the problems……

SAM returns the picture book to BELLE, which makes her very happy. VINCENT’s car is stolen. BELLE’s picture book, which has been kept in the car, is thus lost.

ZOE tries to make it look like an unexpected encounter and honestly expresses her love for SAM……

CHARLIE is coming home, so BELLE helps prepare a room for her. CHARLIE has been on good terms with VINCENT. She has felt ignored since VINCENT’s marriage to BELLE, and is therefore very jealous of her sister-in-law. She and BELLE do bicker a lot, which irks VINCENT. CHARLIE is offered the post of Flight Attendant, and will get training together with BELLE. BELLE confides in RUBY, in the hope of finding a resolution for her conflict with CHARLIE.

She gives ZOE encouragement and promises to help her out wherever she can. SAM and VINCENT are both on the plane, and due to the poor weather conditions, they have to make an emergency landing. They get into an argument about where to land. VINCENT finally follows SAM’s suggestion and SAM is proved right……

SAM feels guilt for having caused ZOE’s injury. He promises he will go to the hospital to see her and to look after her every day, ZOE is therefore thrilled to pieces. BELLE is deeply frustrated by her conflict with CHARLIE. SAM approaches CHARLIE to see what has gone wrong between her and BELLE. He comes to understand that CHARLIE dislikes BELLE simply because she thinks BELLE has stolen her brother. During a training session, CHARLIE means to play a trick on BELLE.
