After a heroin overdose kills his mom, teenager Joshua "J" Cody moves to Southern California to live with his freewheeling relatives. The family's matriarch is J's estranged grandmother, Janine "Smurf" Cody, from whom he's been shielded for years. J soon finds out the reason for the isolation -- Smurf and "her boys" make their livings through carefully planned armed robberies and other criminal activities. Prominent perpetrators are Smurf's relatively level-headed right-hand man Baz and her three sons: mentally disturbed ex-con Pope, hyperactive drug user Craig, and suspicious Deran. In order to stay alive, J must prove loyal to his beguiling grandmother, who rules with a borderline-incestuous love.
