Anton arrives at a summerhouse with his mother and her new boyfriend, on an seemingly innocent mini-vacation. As Anton explores the new environment, he meets Katja and David who seemingly live alone in a neighboring house. Gradually and unsuspectingly, they draw Anton into a dangerous vortex of emotional confusion, where sexual overtures, subtle seduction and surprising violence all play a part. Anton finds himself on the other side of an appalling reality he could not have imagined.
