Four couples at relationship crossroads after seven years of marriage participate in an innovative experiment of switch therapy. Each partner lives with a stranger for two weeks to help determine if different traits and characteristics in a mate could help strengthen their marriage. Psychologists Jessica Griffin and Dan Shapiro help guide the couples through the switch therapy process, as they adjust to living with an experimental spouse. Will their temporary partners be able to fill the void they've been yearning for, or will they discover that the grass isn't always greener? At the end of the monthlong experiment, each of the married couples decide to either part ways and divorce, or reaffirm their commitment and renew their vows.
