Ginger and Brigitte, two high school sisters who have yet to get their periods, are outcasts in their small Canadian suburb, and proud of it. The two obsess over death, making suicide pacts and staging fake demises for a school art class. Things start to change, however, when Ginger finally gets her period and is subsequently attacked by a vicious animal. Suddenly Ginger is interested in boys, and begins to drift from her devoted sister. But that's not the only change Ginger's going through.
