George Hamilton stars as Dr. Mark Collier, who is writing a book on hypnosis, which is his specialty. He is also romantically involved with one of his patients, a Nadia Donner,(played by Lesley Anne Warren) who has a troubled mind, and a jealous, hot-tempered husband that Collier must kill in order to protect himself and Nadia in their beach house after his attack. Unfortunately, he doesn't claim self-defense, but instead instructs her to repeat a story of masked intruders being responsible. Lt. Columbo(Peter Falk) doesn't buy it, forcing Collier to drastic action that may be his undoing... Clever episode with effective performances and a nice twist ending.
