When a meteorite crashes down in the grounds of an American ladies' college, only ASHLEY ROWE, the art teacher, accepts the impossible existence of an alien and its tortured servant, KATIE, a former UFO ubductee. Accepting the alien as real precipitates the nightmare battle to destroy it before it inseminates the girls at the college and creates more of its own kind.
ASHLEY enters the ancient tunnels below the college with LOUISE, one of his students; both determined to free KATIE and stop the monster. But they face more than just the rage of a mindless beast. The police, led by LIEUTENANT MOORE, believe Ashley to be guilty of the terrible crimes committed by the alien and pursue him into the tunnels.
In a monumental showdown, Ashley and Moore must join forces to destroy the alien. Ashley must choose between his love for the dark haired tortured beauty of KATIE or the unquestionable love of brave Louise.
