Chase Walker is not your average man—he is a professional shark hunter, fearless and reckless, with a reputation for tackling the deadliest predators of the sea. When his estranged brother Jake, a ruthless crime boss, offers him a job unlike any other, Chase reluctantly agrees. The mission sounds bizarre even by his standards: a black-finned great white shark has swallowed a rare and priceless diamond during a botched underworld exchange. Recovering the gem means tracking and killing the shark before rival criminals get their hands on it.

Armed with his skills, charm, and stubborn confidence, Chase dives into the dangerous hunt. But the ocean is not his only enemy. Nix, a powerful rival gangster, also desires the diamond and will stop at nothing to claim it. What begins as a straightforward job quickly spirals into a deadly game of cat and mouse, both at sea and on land. Alongside Jasmine, a strong-willed woman with her own motivations, Chase navigates shifting loyalties, violent confrontations, and the ever-present threat of the massive shark lurking beneath the waves.
As the stakes rise, Chase must confront more than just a predator and a criminal rival—he must face his own reckless impulses and his strained bond with his brother. The line between survival and greed blurs, forcing him to decide whether the diamond is worth the blood it demands.
Packed with action, crime intrigue, and a touch of dark humor, Shark Killer offers a wild blend of gangster drama and shark-thriller chaos. At its core, it’s a story of survival, family tension, and the high cost of obsession—set against the backdrop of both the unforgiving ocean and the treacherous criminal underworld.
