Ryan Marks, a decorated former soldier, returns to his native London for his father's funeral only to have his grief interrupted by a violent incursion from Tony Sharp, an ambitious crime lord who seizes the opportunity to claim the Marks family's criminal territory now that its patriarch is dead. With his mother, brother, and sister taken hostage during the ambush, Ryan finds himself pulled back into the underworld he'd left behind, forced to navigate a dangerous criminal landscape to protect his loved ones. Sheltered in a safe house, Ryan embarks on a calculated campaign to dismantle Sharp's organization and neutralize the threat before it consumes his family completely.
