Lupus Perditus - Der verlorene Wolf (2015)

Guilty of his wife's death, Sven flees into the forest to put an end to his life. Unable to pull the trigger, he is about to retreat in defeat when he suffers a life-threatening injury. He spends the next few days trapped under tree trunks. His only contact is a dog, which he believes in his delusions to be a wild wolf. While the voices in his head almost drive him mad, his rage grows and with it his will to live.
