The expert team of matchmakers pair up the first two couples and the cameras follow the preparations for their big day. How will they react on meeting for the first time at the wedding ceremony?

Two pairs of newlyweds wake up in their beds for the first time as husband and wife. The last two couples are matched up by the experts and all eyes are on them as the wedding ceremonies begin.

The four pairs of newlyweds spend a week getting to know each other on their honeymoons. An expectation of romance and intimacy hangs in the air, but not all of the couples are comfortable together.

After knowing each other for only a week, the couples move in together. There's nowhere to hide and emotions run high as they grapple with sharing their personal space on an intimate level.

A dinner party occurs, attended by all four pairs of newlyweds. The couples compare the strength of their own relationship with those around them, but no one is prepared for the fireworks that ensue.

Decision day is just over a week away and the couples are feeling the pressure as they weigh up the strengths and weaknesses of their union. They also face the test of a weekend with the in-laws.

With just 72 hours to go, the couples temporarily separate and avoid all contact with each other while they seek the counsel of friends and family. The stakes are high and hearts are on the line.

The experiment comes to an end as the newlyweds decide: will they stay in their relationships or cut their losses? Two months later, cameras revisit participants to see which pairs are still together.

We meet our first four singles and follow them and their families as they prepare for the biggest day of their lives – a day that should see them say "I do" to a complete stranger.

A day earlier, our first two couples were complete strangers. Now, the morning after the wedding, they wake up together to their new reality as husband and wife. Meanwhile, six more singles come together to comprise our final three couples.

Four weddings down, one to go, and it looks like our expert matchmakers are on a roll as couples three and four get hot and heavy at the wedding reception. But is it love or lust at play?

Following on from the intensity of the weddings, the honeymoon is the first time our couples will have spent any real time alone together, and they will all be asking themselves: is this relationship really going to work?

Our couples are set to return from their honeymoons and enter the third phase of the experiment: moving in together. But pressure is mounting on some couples as they grapple with trust issues compromise.

This season's dinner party will push everyone to the brink. Until now, our couples have existed in a vacuum without contact with one another. Tonight this will change as they size each other up and question the strength of their own relationship.

Our three final couples may have survived the dinner party, but no one has emerged unscathed. Cracks are beginning to appear everywhere, even among the most unlikely of couples. How will this affect the couples as they meet their in-laws?

It's crunch time for our couples as they meet with our expert matchmakers and reveal whether or not they will continue their relationship beyond the experiment. It's a decision that will change their lives forever. Who will stay and who will go?

The couples who have renewed their vows return home and face the reality of a long distance relationship.
