A hundred years later, Tomás, a struggling novelist and the last descendant of the Mariño family, returns to the village on invitation from its mayor to participate in a ceremony and to seek inspiration within his childhood home: a large and abandoned mansion.
Under suspicion from the village and in light of gruesome deaths having happened the night before, Calisto is sent down into the labyrinth to kill the werewolf as the curse is presumed to have remained in effect.
Tomás' grandmother, Rosa (Mabel Rivera), arrives at the same moment, taking the group into her car and escaping to the family mansion.
Tomás and the group are forced to leave the mansion after the werewolves invade it, but are rescued by the policeman revealed to have faked his suicide by letting the bullet only graze his scalp.
The church's explosion and Luis' lack of radio response have attracted the police's attention, and rescue teams arrive at daybreak to find the mass of dead werewolves.
Suspicious that Calisto and Mario might have been bitten by the werewolves and infected, Tomás chains them to a piece of furniture in his home and stands guard with a shotgun in case they turn.
