Mary and Michael are married and in love, just not with each other. They're both in love with other people. Each of them is having a great affair with someone else, and Mary and Michael are actually considering divorcing each other to set up house with their new partners.
Maybe that's why they start falling in love again. Only this time, with each other.
It seems ideal. Only now they're technically cheating on the people they were cheating on each other with. Things begin to get confusing.
A "comeback" film for Debra Winger, who has mostly been hanging around television these last few years.
