Ginger fully transforms into a werewolf on the way home and escapes the van. Aware that she has transformed, Sam and Brigitte hide in the pantry as he makes the cure. When he goes to find Ginger, Ginger mutilates Sam. Brigitte picks up the dropped syringe and follows the blood trail downstairs. After finding an injured and bloody Sam she tries to save him by drinking his blood in an attempt to calm Ginger, but can't go through with it. Ginger sees Brigitte's revulsion and kills Sam in front of her by biting him in the jugular.
As Ginger stalks Brigitte through the basement, Brigitte returns to the room where they grew up. Finding the knife that Ginger had been using to remove her tail, Brigitte holds the cure in one hand and the knife in the other. Ginger lunges at her, becoming fatally stabbed with the knife. Brigitte lays her head upon her dying sister's chest and sobs.
