Psychologist Margot Welles is taking a "sabbatical" from her marriage to explore her "untapped feminine potential" by giving lesbianism a whirl. Hoping to make Margot jealous, her husband Phillip, a philosophy professor, starts dating the lovely Antonia... a much older woman. Margot and Philip both employ their best friend Brighton, a romantically disadvantaged film professor, to keep one another posted... but Brighton's "gay best friend" duties are waylaid when his former student Nick begins to court him out of the blue. Mayhem ensues.
