Ginger Snaps 2

Brigette is an addict. After mixing blood with her late sister Ginger in an attempt to learn more about the condition, she has been infected with "the curse." Each day the curse in her grows stronger and she must increase her dosage of injections. When she is found laying face down in the snow after a near-escape from another beast, she is thrown into drug rehabilitation- locked behind doors without her life-saving antidote.
