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?

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?
