Alvin and Ellie met as students at university and fell in love. Ten years later, they are married with successful careers and very little time for each other and are dangerously close to falling out of love. As the marriage of their closest friends, Peter and Janet, hits the rocks after Peter embarks on a steamy affair, the Finkels begin to analyze their relationship and wonder if they have a marriage worth saving. Do they stay together and continue with their increasingly stale relationship, or should they attempt to relight the flame that they are both missing? Alvin and Ellie are about to discover whether swinging is the answer to their marital problems.
