"Captain, contact's engine noise ceased…she's on her way down." The year 2000. A Russian submarine, the Kursk, explodes in the Barents Sea. Nearby, a British vessel on a secret military mission witnesses its final minutes. The crew must decide whether to blow their cover and go to the survivors’ aid or obey orders and leave them behind. Inspired by true events, Kursk explores the secrecy, camaraderie and hardship of life in the sea’s depths. Over 15s only. Valid ID may be required.
