Director J.T. Petty delves into the twisted world of underground horror movies to see what makes shock cinema, from "Peeping Tom" and "The Texas Chainsaw Massacre" to today's "torture porn" titles, so appealing to modern society. Interviews with filmmakers, actresses, scholars, and others offer insight into the fascination with gore, but one subject leads Petty to the disturbing conclusion that the line between fictional and real-life horror may have been crossed...fatally. AKA: "Sandman." 85 min. Soundtrack: English; Subtitles: Spanish.
