Rumors features four couples that have gathered at the home of a deputy New York City mayor and his wife to celebrate their 10th wedding anniversary. The party never begins because the host has shot himself in the head (it's only a flesh wound), and his wife is missing. His lawyer's cover-up gets progressively more difficult to sustain as the other guests arrive and nobody can remember who has been told what about whom. Hilarity abounds as the couples get more and more crazed and when the police arrive, the evening unravels into a series of quick changing lies.
