The "feature film" Death Follows the Psycho is actually comprised of footage culled from the 1973-74 TV series Griff. Lorne Greene stars as Wayne "Griff" Griffin, a former police captain who becomes a private eye after the murder of his patrolman son. Ben Murphy costars as Griff's assistant Mike Murdoch. Most of Death Follows the Psycho consists of the 60-minute Griff episode "Countdown to Terror," which first aired November 17, 1973. Ricardo Montalban guests as a "human time bomb," who threatens to blow up four hostages unless Griff delivers the man Montalban really wants to kill.
