In this high-octane action thriller, 12 Rounds 3: Lockdown follows John Shaw (Dean Ambrose), a determined and morally upright detective who returns to duty after recovering from a gunshot wound sustained in the line of duty. However, his comeback is anything but smooth when he stumbles upon evidence implicating his fellow officers in a massive drug and corruption ring.
When Shaw’s discovery threatens to expose the truth, the corrupt officers, led by the ruthless Detective Burke (Roger Cross), move swiftly to silence him. Trapped inside his own precinct, Shaw must rely on his training and resourcefulness to outwit and survive the relentless assault of his former colleagues. With the building locked down and no way out, Shaw finds himself in a deadly game of cat and mouse where every second counts.
