Inspired by a true story, "K-19: The Widowmaker" follows Captain Alexei Vostrikov (Harrison Ford) who, at the height of the Cold War, is ordered to take over command of the nuclear missile submarine K-19, pride of the Soviet Navy. His assignment: prepare the K-19 for sea and take her out on patrol - no matter what the cost. But problems with K-19 arise that may lead to a core meltdown and explosion that will certainly kill all aboard, and possibly trigger a nuclear war. In a daring act of heroism, Vostrikov must choose between his orders from the Kremlin and the lives of his men. As the K-19 heads toward American waters, a shocking discovery is made: the vessel's nuclear reactor system is leaking, imperilling the men and the sub's missiles. With time running out, the fearless Vostrikov and his crew join together as brave countrymen who must decide the true meaning of duty, honour and sacrifice.
