With their relationships on the rocks, each week one couple takes the plunge to spend five days together on a secluded island deep in the South Pacific to try to rectify their marital issues. Left alone with no modern conveniences and limited access to food and water, these pairs have only each other to rely on as they navigate the challenging and treacherous conditions on the island. The couples must complete a series of physical and emotional exercises specifically designed by marriage experts to solve the serious issues tearing them apart. Guiding viewers through the experience are Dr. Colleen Long, licensed clinical psychologist, and Dr. Tom Kersting, family therapist, who help navigate the couples’ often volatile journeys, where a simple act can unearth years of pent up aggression, regret and pain.
