1975, Swiss Alps: In a remote mountain village, a woman of wild beauty appears seemingly out of nowhere. Only the village policeman Reusch takes care of the stranger without reservation and tries to find out who the mute woman is. There are increasing indications that the woman has come down from the high alpine pastures, where alpine dairymen in their loneliness do a lot of unimaginable things to get female company. In the process, what would have been better left hidden comes to light. A tragedy of lust, madness and murder pours over a seemingly perfect idyll.
