Larry Kozinski (Danson) and Maria Hardy (Rossellini) meet at the marriage of Larry's uncle Phil and Maria's mother Edie (Aleandro). Newly made cousins-by-marriage, they find they have more in common than expected, as their respective spouses, insecure Tish (Young) and boorish Tom (Petersen) begin an affair. Over a series of ritualized family events, dreamer Larry and repressed Maria decide to exact revenge on their spouses by pretending to have an affair themselves. Their good-natured plan takes on unexpected gravity when they learn not only are they great friends, but they realize they're falling in love with each other. This is an American remake of the 1975 French comedy "Cousin Cousine", directed by Jean-Charles Tacchella.
