Reports of Bigfoot sightings in upstate New York reach noted anthropology professor Ernst Prell. He recruits some of his students to help investigate the rumors. Lodging at a cabin in the woods, the coeds are more interested in turning the expedition into a sexy sleepover. Playtime is over when the sasquatch actually appears, hunting them one by one. But Prell's star student, Keith, suspects that the monster is not what it seems. The truth behind the legend of Bigfoot is about to be revealed...a secret more terrifying than imaginable... <P>A staple of the midnight movie circuit and late night television, <I>Shriek of the Mutilated</I> is the work of director Michael Findlay and cinematographer Roberta Findlay. The husband and wife team are best known for their adult films such as <I>The Sin Syndicate</I> (1965, starring a young Yoko Ono) and <I>The Touch of Her Flesh</I> (1967). They were also responsible for the notorious <I>Snuff</I> (1976), a low-budget horror movie that masqueraded as an actual snuff film. They became involved with <I>Shriek of the Mutilated</I> when they did a last minute editing job on writer-producer Ed Adlum's prior film, <I>Invasion of the Blood Farmers</I> (1972). The Findlays had a falling out with Adlum during production, which perhaps accounts for the shocking twist at film's end. Michael Findlay died in 1977, decapitated by a detached rotor blade while boarding a helicopter to Paris. Roberta became a noted horror director in her own right, with films including <I>Tenement</I> (1985), <I>Blood Sisters</I> (1987), and <I>Prime Evil</I> (1988).
