The film is based on a true story. K19 is the first strategic nuclear submarine of the Soviet Union. Film director Catherine Bigelow is the first Oscar winner for best female director. Captain Alexis (Harrison Ford Harrison Ford) is ordered to succeed former captain Mikhail (Lemnison Liam Neeson) as commander of the nuclear-powered missile submarine KMel 19 at the height of the Cold War. Alexis's mission was to put the improperly maintained submarine on operational alert and carry out its maiden voyage as soon as possible at all costs. But the two men and the loyal officers and soldiers of the whole ship had no idea what mission they would carry out. They also have no idea what the cost of failure will mean to them and the world. At that time, a nuclear reactor malfunctioned, a dangerous fuel rod was about to melt and a nuclear explosion occurred, which would certainly cause all the people on board to die at the bottom of the sea. When they were cruising at the bottom of the Arctic Ocean, it was the bravery of the crew and the captain's sense of responsibility to the country and crew that finally saved Kmur19 from an impending nuclear disaster.
