He reaches out to his estranged grandmother, Janine "Smurf" Cody, who warmly welcomes him into her home. J quickly realizes that his grandmother and uncles are entrenched in a life of crime. The Cody family, led by the cunning Smurf and consisting of her three criminally active sons, are under constant surveillance by the police. J is reluctantly pulled deeper into their dangerous activities and must navigate the treacherous dynamics within his new family environment.

Torn between familial loyalty and his sense of morality, J is caught in a relentless moral tug-of-war. The pressure mounts as the situation grows more perilous, forcing J to make critical decisions that will determine his future and his allegiance.
