I can't say for sure whether or not Jeff Leroy's Werewolf in a Women's Prison was intentionally made to cash in on the publicity of Grindhouse. The title does sound suspiciously similar to Rob Zombie's fake trailer Werewolf Women of the SS, and the film does imitate the same style that Grindhouse tries to emulate. In any case, while there are few areas where this low budget effort could hope to compete with Rodriquez and Tarantino's ode to trash cinema (which, despite disastrous box office, I loved), WIAWP actually manages to come closer in some ways to the grindhouse cinema formula. One of the film's greatest assets is it's trashy title that suggests a meeting of two of the great exploitation genres: horror flicks and women in prison movies. Second, it pretty much wallows in the time-honored combination of sex and violence, achieving a degree of 70's style political incorrectness that Tarantino and Rodriguez could never have attained while still getting an R rating.
Sarah Ragdale (Victoria De Mare) and her boyfriend Jack (played by co-screenwriter Vinnie Bilancio) are camping in Mexico when they are attacked by a werewolf. Jack is mauled to death, but Sarah is able to kill the creature with vodka laced with silver flakes, though not before she herself is bitten. Sarah awakens in Canpuna State Prison For the Criminally Insane and, not surprisingly, no one believes her story. The rat-infested prison is run by a ruthless thug named Juan (Domiziano Arcangeli) and his colleague Mistress Rita (Jackeline Olivier), who reminds me a lot of the title character from Ilsa, the Wicked Warden. Most of the inmates have been falsely accused of crimes, so Juan and Rita can exploit them, using them for prostitution and as models for their Prison Girls Gone Wild website.
