Deep beneath the ocean's surface, a high-stakes military thriller unfolds as Captain Joe Glass (Gerard Butler), a maverick American submarine commander, finds himself thrust into a covert rescue mission after a top-secret submarine goes missing in Russian waters. When a daring SEAL team led by Bill Beaman (Toby Stephens) is deployed to investigate, they uncover a military coup that threatens to ignite World War III. Meanwhile, Glass must navigate treacherous underwater terrain and outwit a rogue Russian admiral, all while maintaining fragile communications with Admiral John Fisk (Gary Oldman) and Rear Admiral Donnegan (Billy Bob Thornton) back at the Pentagon. With time running out, Glass forms an unlikely alliance with Russian Captain Sergei Andropov (Michael Nyqvist), a prisoner on the run, to prevent global catastrophe. Directed by Donovan Marsh, this pulse-pounding action thriller combines claustrophobic submarine warfare with explosive land-based combat, delivering edge-of-your-seat tension as ordinary men are forced to make extraordinary choices to save millions of lives.
