After escaping a Puget Sound institution, "Stepfather" Gene Clifford alters his appearance with plastic surgery and takes on another new identity: Keith Grant. Moving to Deer View, California, Keith falls for a divorced school principal, arousing the suspicions of her wheelchair-bound, computer-savvy son.
Unfortunately the movie Stepfather 3 is not yet available on HBO Max.
