A group of American University students go to England to study the old Celtic legends and come face to face with a tribe of inbred mutant cannibals that have existed since the Middle Ages. Actor Richard Grieco, with weird long hair, appears for five minutes and Bobbie Phillips (CHAMELEON 1-3) is the chaperone. The monsters live underground in tunnels, but the set design is so cheap that all the stone walls look like the styrofoam that they are.
The inbred mutant cannibals are nasty looking, along the lines of HILLS HAVE EYES 2, but the story sucks, the acting sucks, and the set design really sucks. A triple suck movie.
