Sarah and Charlie, a married couple, run a small theatre that’s presenting A Christmas Carol — until Charlie shows up backstage to say the cast and crew are snowed out. Charlie is planning to split up with Sarah tonight, but he’s snowed in. Sarah, furious, capitalizes on Charlie’s remarkable memory, and blackmails him into doing the play with her as a duo, relying on scripts when they need to. He plays Scrooge; she plays everyone else. As the performance proceeds, Charlie gets drawn back into his relationship with Sarah. They actually manage to perform much of the play, with their personal story invading the Dickens tale, informing it with dual levels of meaning.
