The film is based on a true story. K19 is the first strategic nuclear submarine of the Soviet Union. The film's director Kathryn Bigelow is the first winner of the Oscar for Best Female Director. Captain Alexi (Harrison Ford) received an order to replace the original captain Mikhail (Liam Neeson) as the commander of the nuclear-powered missile submarine K-19 at the most tense moment of the Cold War. Alexi's mission is to put this improperly maintained submarine into combat alert as soon as possible at all costs and perform its maiden voyage. But the two and the loyal officers and soldiers on the boat never thought about what mission they would perform. They could not foresee what the cost of failure would mean to them and the world. At that time, a nuclear reactor malfunctioned, and a dangerous fuel rod was about to melt and explode, which would definitely bury all the people on the boat. They were cruising on the bottom of the Arctic Ocean at the time. It was the bravery of all the crew members and the captain's sense of responsibility to the country and the crew that ultimately saved K-19 and avoided an impending nuclear disaster.
