of his family's ancestral home in Rittersberg, Germany. While seeking inspiration for a new manuscript, Gabriel finds himself assuming his family's responsibility as a "Schattenjäger" ("shadow hunter") – a role his ancestors have assumed in combatting supernatural evils – when the townsfolk call for his help. Sent to Munich to investigate a spate of killings around the city, he discovers evidence that they are the action of a werewolf, despite the belief by local police, led by commissar Thomas Leber, that they are being committed by two escaped zoo wolves. Discovering the events are linked to a local hunting club, Gabriel seeks entry as a new member.

Investigating the club further, he begins to suspect Von Zell's involvement in the killings, and when invited to an annual hunting trip by Friedrich, Gabriel finds evidence confirming him to be a werewolf. After witnessing him consuming several corpses in a cave, Gabriel reveals his findings to Friedrich, who, horrified of what he
