The McLusky family are powerbrokers in one Michigan community, with the ability to mould and destroy lives. Mike McLusky (Jeremy Renner) reluctantly inherited the position of mayor from his late older brother Mitch (Kyle Chandler) in a town where the only lucrative business is incarceration. The clan is led by fiery matriarch Miriam (Dianne Wiest), who teaches inmates at the female prison, while Mike's younger brother Kyle (Taylor Handley) works as a detective for the Kingstown Police Department, partnered by seasoned officer Ian Ferguson (Hugh Dillon). The McLuskys often take the law into their own grubby hands and following the riot at the prison, they may have to bend the rules again to restore some semblance of peace. Behind bars, menacing Russian mobster Milo Sunter (Aidan Gillen) exerts his poisonous influence over Kingstown and its corrupt denizens.
