Somewhere in the lush French countryside, a spate of unaccountable disappearances of unsuspecting female skinny-dippers terrorises the superstitious inhabitants of a close-knit lakeside community. As the efforts of the town's mayor to shed light on the mystery remain fruitless, the hair-raising story of the infamous lake of the damned, where a squad of Nazi soldiers met their end during WWII, chills the bone to the marrow.
