David gives his wife, Joyce, an unexpected—and unpleasant—surprise when he suddenly demands a divorce. When she then learns that David has taken up with a younger woman, Joyce decides to make the most of this separation by taking a solo trip to the Caribbean. However, just before diving into a vacation fling, she runs into Emily, an old chum whose own divorce has left her embittered. Joyce then debates giving married life one last chance.

The wedding of Ellen and David is halted by a stranger who insists that the bride is already married to someone else. Though the flabbergasted Ellen denies the charge, the interloper produces enough evidence that his accusation must be investigated. Ellen and David travel to the small coastal town where her first wedding allegedly occurred. There, they meet a number of individuals whose stories make Ellen question her own sanity.
