In Bailey Downs, a rash of dog killings has been occurring. Brigitte and Ginger Fitzgerald are teenage sisters who harbour a fascination with death and, as children, formed a pact to die together. One night, while on the way to kidnap a dog owned by school bully Trina Sinclair, Ginger begins her first period, which results in the girls being attacked by the creature responsible for the maulings. The creature wounds and bites Ginger, but Brigitte rescues her. As the girls flee, the creature is run over by a van belonging to Sam Miller, a local drug dealer. Ginger decides not to go the hospital as her wounds heal quickly.
