Based on a true account of the M.O.N. murders, four friends experience firsthand the psychotic mind of a madman, as told through one of the most bizarre letters written by an anonymous source calling itself M.O.N. This film is a word-for-word representation of the events that unfolded on these four youths in Goatshead, California. Nothing could prepare them for the unspeakable insanity that they would encounter not only around them…but also in their own minds.
