Paper Covers Rock (2008)

PAPER COVERS ROCK tells the story of Sam, a troubled young woman who loses custody of her six year-old daughter in the wake of an unsuccessful suicide attempt. Following a brief stay at a psychiatric facility, Sam moves in with her older sister Ed, who graciously offers to help Sam piece her life back together. But the road to hell is paved with good intentions, and it's not at all clear whether Ed is out to save or destroy her little sister.
