In a state ruled by four powerful mafia groups—Heart, Spade, Clover, and Diamond—each crime syndicate operates under a strict hierarchy modeled after a deck of cards. The Kings reign as ruthless leaders, the Jacks serve as their trusted right-hand men, and the Aces are the most valuable yet independent assets. But beneath this system of order lies a web of betrayal, power struggles, and a fractured past. An unfortunate turn of events forces Vincent "Vin" Archer into the Clover group. How will he survive?
