Ex-soldier Frank is haunted by a violent past. He lives alone, drowning his nightmares with alcohol. Christine, on the surface smart and successful, tackles life as a single working mother by immersing herself in drugs, parties, and sex. Lynette, a young rough-sleeper, watches Christine stumble out of a club while she sits in the cold waiting for loose change to fall into her lap; her luck seems to change when she meets Frank, who--despite his misgivings--offers her a place to stay.
