Watch Mompelaar (2008) Official Trailer

Mompelaar is a man who lives with his ever present and overbearing mother; he appears to be entirely introverted and have a speech impediment that sees him entirely incomprehensible. He heads out into the woods and finds himself at the place where several brutal murders appear to have occurred. He tidies up a bit and carries on, coming across a group out for a nature talk which descends quickly into horror and religion.
