Couples Retreat Soundtrack

Synopsis: Dave and Ronnie, Jason and Cynthia, and Joey and Lucy are close. The group used to include Shane and Jennifer, but they divorced and she's gone. Jason and Cynthia announce that their marriage is in trouble, and they beg their friends (and Shane's young girlfriend) to join them on a couples' retreat, at the package rate, on a tropical island. The others reluctantly agree, planning to play while Jason and Cynthia work on their marriage with an island psychologist. To everyone's surprise, the package is inflexible: each couple must participate in the couples' exercises. Soon fault lines appear in all four relationships. What's in store for each couple?
