Stepfather III (also known as Stepfather III: Father's Day) is a 1992 American slasher film directed and written by Guy Magar. It stars Robert Wightman, Priscilla Barnes, David Tom, and Season Hubley. It is the second sequel to 1987 film The Stepfather and a follow-up to 1989 film Stepfather II. The film follows a serial killer seeking out another family to become a part of, using plastic surgery to disguise himself from the authorities. Unlike the previous two installments, Stepfather III was released made-for-television and Terry O'Quinn does not star in the titular role.

Plot

Having survived the stab wounds he sustained in Palm Meadows, Los Angeles at the end of the previous film, Gene Clifford escapes from the same institution in Puget Sound, Washington he was placed in four years ago. He seeks out a back alley plastic surgeon to alter his appearance, using no anesthesia. After a few days, Gene kills the doctor by slitting his throat with a bone saw and makes his way to Deer View, California, where he acquires a new identity, "Keith Grant", as well as a small cottage and a job at a plant nursery. Nine months after crafting his new life, Keith, during an Easter dance held by the church, meets divorced school principal Christine Davis and her psychosomatically paralyzed son Andy. Keith and Christine begin dating. When Christine's possessive ex-boyfriend Mark Wraynal follows Keith home and confronts him, Keith offers to have a chat. Keith kills him with a shovel and buries the body in his garden.
