When childless Peter Lovett admits to his wife Fran to be gay, many oddities suddenly make sense. They agree to separate, but for financial reasons still share the large house while real estate prices are too low. Six months later, Peter has fully embraced a queer lifestyle and Fran finally dates a great catch, studly music producer Elliot.
Peter grudgingly lets Fran have the house a night to make love with Elliot. Peter gets drunk and ends up unwittingly crawling in the former marital bed, spooned between Elliot and Fran. When that becomes clear in the morning, Elliot leaves horrified. Her parents refuse to let Fran move in again, so instead of moving out she settles for house rules agreed with Peter, yet meanly ruins his most promising shot at a gay date.

Neverheless, actually being and dining alone is no fun, she even realizes fear of loneliness made her blind for Peter's 'oddity'.
Peter and Fran go to the movies together and bump into Elliot, who she wants back, but seeing him with a woman she takes her parents' advice to forget about him. Internet dates are easy to get, by far from satisfactory. Then Peter finds out Elliot was with his sister, so they assume him still a bachelor.
