Viewers learn each of their love stories--how they met, how they fell in love, how their marriages took a turn for the worst and why they are willing to risk everything in order to save it.

The switches have been made and the experimental married couples are getting to know each other while also navigating their new living quarters and sleeping arrangements.

It's the first week of the experiment and the couples are exploring each other's passions, personalities and patience.

While away on a weekend getaway, the experimental married couples are faced with challenging situations that will force them to either open up or shut down emotionally.

Now that the experiment is almost half way through and the couples are invested emotionally, Dr. Jessica pays a visit to all of the experimental married couples in order to check in and give them some surprising news.

The experiment is coming to a close but before the couples are sent home, they're faced with their biggest challenge yet.

The married couples are reunited back home and share their experiences, revelations and concerns with one another while trying not to fall back into their old routines.

Two weeks have passed since the married couples have reunited and now they're challenged with the decision of whether they've made the right choice with their spouse or whether it's time to part ways for forever.
