Madman (1981)
These standard slashers don’t really need a synopsis but here we go! – Under a campfire on a dark night Max (Neumann), owner of a camp for gifted children, tells staff and campers the tale of Madman Marz (Ehlers); a deranged farmer who slaughtered his family in a nearby house. Legend has it that if you speak his name above the sound of a whisper he’ll come for you.
