Arriving home from a business trip, Frank Delgado (Alejandro Rey) finds that his wife Margo (Katherine Justice) has been entertaining his client Alan. In a jealous rage, Frank accosts Alan as he leaves his house, strangling him to death. After disposing of the body, Frank returns home, but the police are soon on his trail.
Believe it or not, drive-in flick The Stepmother was nominated for an Oscar in the best song category; it didn't win, but it's an interesting fact for avid fans of low budget '70s trash, the only people for whom this film will hold any kind of appeal.
A tawdry drama/thriller, The Stepmother is far from great cinema, suffering from a meandering storyline that takes an age to go anywhere, but it does deliver a few fun elements along the way, including those staples of the exploitation genre, violence and nudity (including the obligatory shower scene).
The film also features a spot of jazz flute (always a bonus in my book), bizarre use of random slo-mo and freeze frame, a crazy film director called Goof who uses beatnik speak (It's a gas! You dig?), a seduction scene between Margo and Frank's virginal son Steve (Rudy Herrera Jr.), and a couple of moments that I found unintentionally funny (the death of Frank's friend and the 'He's got a gun!' ending).
Worth seeing if only for the beautiful Ms. Justice. 4/10
