Ginger Snaps is a 2000 Canadian supernatural horror film directed by John Fawcett and written by Karen Walton, from a story they jointly developed. The film stars Emily Perkins and Katharine Isabelle as Brigitte and Ginger Fitzgerald, two morbid teenage sisters whose relationship is tested when Ginger (who has started her period for the first time) is attacked and bitten by an unknown animal, and then later, during the next full moon, slowly starts to transform into a lycanthrope (werewolf). The supporting cast features Kris Lemche, Jesse Moss, Danielle Hampton, John Bourgeois, Peter Keleghan, and Mimi Rogers.

Plot

In Bailey Downs, a rash of dog killings has been occurring. Brigitte and Ginger Fitzgerald are teenage sisters who harbor a fascination with death, and as children, formed a pact to move out of the suburb or die together by the age of 16. One night, while on the way to kidnap a dog owned by school bully Trina Sinclair, Ginger begins her first period. The scent of blood results in the girls being attacked by the creature responsible for the maulings. The creature bites Ginger. As the girls flee, the creature is run over by a van belonging to Sam Miller, a local drug dealer.
