With less than a month to go, the couples focus on how they can improve communication with their spouses before they have to decide if they want to stay married or get a divorce. The couples' trust and honesty are tested when they are asked to trade cell phones for an hour without warning.

The couples are forced to examine if they are on the same page about what they want out of marriage. The future seems uncertain for one couple when a spouse admits he wants to keep his own apartment, even if they stay together.
