Nine teenagers and a 10-year-old boy are planning on having a school trip they will never forget. However, they get more than they bargained for when their plane crashes and they end up stuck on an island with nothing but canned food, an airplane, and each other.

Jackson ends up leaving the survivors after a shocking secret about him is revealed, and he decides to travel across the island on his own. However, what he does not know is that a giant monsoon is coming to the island.

Daley & Nathan are still campaigning to be the group leader, but when the kids use a secret ballot, the majority of votes goes to neither Daley or Nathan.

With the camping food running out, Nathan, Daley, and Lex have to find food out in the jungle. Meanwhile, Jackson tries to help out by catching fish and Eric fakes an injury in order to not have to help out at all.

Nathan and Daley nearly get into a fight with Jackson. Meanwhile, to try and bring the survivors together, Lex builds an obstacle course and challenges the others to a competition.

A recently rescued Abby finds that much has changed since the crash, making it hard to fit in with the other survivors.

All the castaways have been making video diaries to document their personal feelings about the trip and each other. After waking one morning, they find that the tapes have been stolen, and they all worry that their secrets will be exposed.

Even though Jackson has been chosen leader, he refuses to accept it. Meanwhile, Daley and Eric continue to search for a source of fresh water to drink; Nathan tries to create a device that will gather water from the air.

When Nathan and Daley fight over who should be the leader of their group, Nathan tries to light a signal fire, while Daley looks for a suitable campsite. Meanwhile, the pilot and three of the kids decide to search the island.

Daley is fed up with Taylor because she isn't doing her share of the work. Meanwhile, Lex & Nathan build a signal kite together.

Eric blackmails Melissa into doing his share of the work. Meanwhile Lex discovers a new food source - raw oysters.

Nathan and Eric discover a distress message that leads them to believe that there is someone else on the island.

Daley and Nathan go pig hunting together. Meanwhile, Taylor spreads a secret about Melissa in retaliation for ruining her shirt.

The kids have to work together and rebuild their shelter after a tropical storm hits.

After Eric discovers a mysterious box that can't be opened, the castaways fantasize about what might be in it.

Eric and Taylor create many conspiracy theories involving Nathan, Daley and Melissa. When confronted, Melissa accidentally reveals that Nathan is in love with Daley.

Eric is to blame when their only source of fire, Jackson's lighter, breaks. Meanwhile, a lizard makes itself at home in the castaways' tent.

The kids must jump into action when the airplane wreckage washes back on shore and traps Nathan underneath it.

The kids decide to convert the plane wreckage into a new shelter.

With hopes for a better chance of survival, the castaways attempt to move the plane wreckage off the beach and head for higher ground.

Trying to raise everyone's spirits, Taylor creates an imaginary holiday called "Chilloween" while Nathan tries to show his love for Daley by making her a bracelet.

Melissa blames herself after Jackson gets sick from drinking unsafe water.

After Eric discovers that there is a current in the ocean around the island, the castaways decide to build a raft. The next morning, Daley and Nathan set sail West trying to head for Asia but disaster strikes.

After Abby left the camp, she tried searching for Ian, Jory and Captain Russell, but got really lost instead and later returns to the camp.

Lex finds a chicken on the island and figures that someone must have brought it to the island. Meanwhile, Abby returns to the camp having not found any sign of the others.
