In this fact-based Swedish movie, 23-year-old Stockholm junkie Sandra (Johanna Sallstrom) nearly dies from an overdose and checks into a rehab home, unaware that her drug pusher roommate Roffe (Mikael Persbrandt) is plying drugs on her 18-year-old sister Jannika (Tove Appelqvist) and forcing her into prostitution. Sandra soon leaves rehab in order to save sis -- while flashbacks reveal the childhood influences they experienced with their now-divorced upper-class father and alcoholic mother.
