Jessica (Angela Lansbury) is summoned to the island retreat of her friend Henry Reynard (Gene Barry), a millionaire lumberman. Someone has threatened Henry's life, and he is convinced that the "someone" is a relative anxious to get his or her hands on the old man's millions. Upon her arrival, Jessica is told that Henry has already been killed--but as she soon finds out, appearances (and first impressions) can be very deceiving!
