Synopsis by Hal Erickson
Sydney Chaplin (son of Charlie) heads the cast of the British meller The Deadliest Sin. Chaplin plays a slimy holdup man named Mike, who has recently double-crossed his partner in crime. When the partner shows up to claim his due, the man is killed by Alan (Peter Hammond), the boy-friend of Mike's sister Louise (Audrey Dalton). Alan is all for confessing his crime, but Mike, realizing that he'll be implicated in the original robbery, murders Alan. Alas, Mike's victim has already spilled the beans to Father Neil (John Welsh), leaving our "hero" no alternative but to knock off the priest as well-and it is this blasphemous decision that results in Mike's downfall.
