The film follows the story of Captain Robinson, a seasoned submarine veteran who has been abruptly laid off from his job with a salvage company. Desperate for money, he is approached by a shady businessman who offers him the chance to lead a mission to recover a fortune in gold that he claims is lost in a sunken Nazi U-boat in the Black Sea.
Robinson assembles a team of British and Russian crew members, including the young and inexperienced Tobin, the stoic Russian mechanic Zaytsev, and the volatile Fraser. Together, they set out on the aging Soviet submarine, the Black Sea, to locate the U-boat and claim its treasure.
As they descend deeper into the ocean, tensions rise among the crew. The claustrophobic confines of the submarine and the mounting pressure of the mission provoke fear and paranoia, causing the crew to turn on each other. Robinson tries to maintain control, but greed and desperation take over as the team moves closer to the prize.
As they approach the U-boat, their efforts are complicated by unexpected obstacles and accidents. The crew's relationships continue to fracture, with Robinson pitted against his own men in a struggle for power and survival.
Ultimately, Black Sea is a tense and gripping thriller, exploring the dangerous consequences of greed and betrayal in the pursuit of riches. The film is directed by Kevin Macdonald and stars Jude Law, Scoot McNairy, and Ben Mendelsohn.
