Ginger (Katharine Isabelle) and Brigitte (Emily Perkins) are two teenage sisters fed up with the routine of high school, dating and parents. They long for something which would bring a little excitement into their lives, but when Ginger is attacked by a werewolf it’s maybe a little too much, too soon.
Over the following months, Ginger undergoes some surprising physical and psychological transformations. Brigitte does her best to fight against the changes and win her sister back, but with Ginger having now infected her boyfriend Jason (Jesse Moss), it seems that she might be fighting a losing battle.
