The return of psycho Jerry Blake (Terry O'Quinn) in Stepfather II proved that he was impossible to kill, and sure enough, here he is again, up to his old tricks despite the claw-hammer to the chest he received at the end of Jeff Burr's sequel. Part three also shows 'the stepfather' to be impervious to pain, the killer having plastic surgery to alter his face (and, miraculously, his voice and hairline) all without the need for anaesthetic. With his new look (the character now played by Robert Wightman, who resembles Jim Carrey with a touch of Christian Bale), the killer once again goes looking for the ideal family unit.
This time, the murderous loony - now calling himself Keith Grant - marries divorcee Christine Davis (Priscilla Barnes), once again without the need of a birth certificate or any kind of legal documentation, but her wheelchair-bound amateur detective son Andy (David Tom) isn't convinced of his new stepfather's apparent good intentions. When Christine learns that she cannot have any more children, and Andy goes to stay with his father for the summer, Grant becomes angry that his family is no longer perfect and starts to romance widow Jennifer (Season Hubley) in preparation for his next move. Meanwhile, Andy has been investigating Grant's mysterious past and begins to suspect that his stepfather is a serial killer.
Those familiar with the series' formula will no doubt know how the film will pan out, Grant killing anyone who threatens to spoil his plans, before turning his murderous intentions to Christine; this time around, the deaths are a tad gorier despite this being a made-for-TV movie (Grant uses a bone saw and a rake, and a wood-chipper comes into play at the end), but this is still a very tired three-quel lacking in originality and genuine thrills, and which, at 110 minutes, is at least 20 minutes too long.
