Lexie Malton is an average Vancouver teen with fairly typical issues. Her stepmother is far from her favourite person, she has a sister with special needs, and life outside the home is the usual mix of school, friends, and social events.

But Lexie has a secret. Her ex-boyfriend, Devlin Mather, is now a heroin addict living on the street, and only Lexie knows that she's the one who put him there. Guilt makes her give in to Devlin's demands for money time and time again, even though she knows how dangerous his drug use is.

Lexie finally gathers the strength to stop enabling Devlin. But when he seeks treatment for his addiction, Lexie finds herself drawn back to him, never guessing what a dark and deadly path she has just chosen.

Devlin relapses, and his desperation leads to an act that will change both of their lives forever.
