NO ONE SAID SURVIVING HIGH SCHOOL WOULD BE EASY.
After spending time at a mental institution, troubled student Brian Woods returns to class amid a swirl of rumors about his emotional state. Brian competes for the affections of Paula with her boyfriend - the school's resident rebel, Dwight. When students begin disappearing at an alarming rate, Brian is the obvious suspect, but the real threat may be coming from an unexpected source.
