A covert operation inside an Aleppo subterranean tunnel ends in catastrophic failure, wiping out nearly an entire Navy SEAL platoon led by Lieutenant Commander James Reece. Reece survives, returning home concussed and plagued by fragmented memories. When hitmen execute his wife Lauren and daughter Lucy in their home, Reece realizes the Syrian ambush was an orchestrated internal purge rather than a combat mishap. Diagnosed with an inoperable brain tumor that leaves him with weeks to live, Reece drafts a target list on the back of his daughter’s sketch and wages an asymmetric war of attrition against high-ranking conspirators.

The fragile peace governing London's criminal underworld shatters when Eddie Harrigan, the reckless grandson of mob boss Conrad Harrigan, murders Tommy Stevenson, the son of rival kingpin Richie Stevenson. Tasked with preventing an all-out turf war, Harrigan family fixer Harry Da Souza scrambles to erase the forensic evidence. However, Conrad and his calculating wife, Maeve, seize the crisis as an opportunity to muscle into the Stevensons' lucrative fentanyl pipeline, igniting a merciless bloodbath across the capital.

When British UN soldier Edward "Eddie" Horniman returns home to his dying father, he unexpectedly inherits the title of Duke of Halstead and the family’s estate, bypassing his erratic older brother, Freddy. Shortly after taking over, the new Duke discovers the shadowy source of his family's income. A massive underground cannabis plantation operates beneath the estate: crime boss Bobby Glass, who runs his syndicate straight from a luxury prison, has been leasing the subterranean grounds for years. Trapped between Freddy’s multimillion-pound debts and the iron grip of Susie, Bobby’s ruthless daughter, Eddie resolves to navigate the criminal underworld just long enough to buy his family’s freedom.
