Sad tale of everyday addiction, portraying the issue with a bleakness that allows for authenticity that few films accomplish. Irene (Farmiga), a mother of two saddled with financial difficulties, begins using cocaine to get through her days working as a cashier in a suburban mega-store. But as time passes, her dependence, lies, and the personal tolls all mount. Eventually she seeks help at a rehab center and meets a nurse, Bob (Dillon), who is also a recovering user. The two become friends as they try to support each other's recovery.
