Peter Chance suffers a blow to the head and wakes up with amnesia in a luxurious home, where a doctor and several women tell him he's a missing heir who's inherited millions. But Peter soon suspects something is not quite right with their story. He sets out to learn the truth before he's forced to sign a document that purportedly finalizes the transfer of the estate. This drama is based on Hugh Wheeler's novel Puzzle for Fiends.
