Released in America under titles like New House On The Left and Second House On The Left, the 1975 Italian exploitation film Night Train Murders crudely follows the template for Wes Craven’s notorious 1972 rape-revenge thriller The Last House On The Left. Act one: Two attractive young women venture off on their own. Act two: Sadistic thugs subject them to violence, degradation, and sexual assault, then leave them for dead. Act three: The perpetrators wind up in the house of one of the victims’ parents, who slowly realize what happened to their daughter. As facsimiles go, it’s mostly mediocre, absent much of the raw horror and intensity of Craven’s film, and not that distinct from the many ’70s Italian genre films pipelined into American grindhouses. But vive la différence: By making the film’s true lynchpin a bourgeois nymphomaniac who eggs the attackers on, director Aldo Lado and his screenwriters add a layer of social commentary that’s entirely their own—and, not coincidentally, by far the film’s strongest element.
