Matthew's wife, Lisa, is having an affair with Adrian, a British director. Or perhaps the affair is part of a play being rehearsed. Or perhaps Matthew has imagined it all. But a mysterious woman who seems to shadow the others brings the story to its surprising conclusion…or does she? The audience plays the role of detective in this hilarious, multi-layered comedy of suspicion about love, lust, and the power of deception in which nothing is ever quite what it seems.
