When seventeen year old J's mother dies of an overdose, he calls his grandmother, Janine "Smurf" Cody, who invites him to come live with her. A Ma Barker camouflaged as a cheery suburban grandmother, she dotes on her roguish boys, and looks to add J to the mix. The oldest is Pope, a gunman off his meds, unhinged drug dealer Craig, and baby-faced youngest Darren. The brothers, along with Pope's friend Baz have been running a very successful armed robbery business. J's just looking for a home, but he's caught between the sociopathic Pope and a cold, methodical police sergeant who wants the Cody's bad. Now J must become a survivalist, navigating unsteadily but instinctively between his unscrupulous grandmother and the dirty cops, trying to escape the poisonous grip of both.
