In 1961, the
Soviet Union launches its first
nuclear-powered ballistic missile submarine, the
K-19, commanded by Captain Alexei Vostrikov, with
executive officer Mikhail Polenin, the crew's original captain. Vostrikov is alleged to have been appointed through his wife's political connections, and because of Polenin's tendency to put crew morale and safety before Soviet pride. Discovering the reactor officer drunk and asleep on duty, Vostrikov fires him, receiving a replacement, Vadim Radtchenko, fresh from the academy. The launch is plagued by misfortune; the inaugural bottle of champagne fails to break on the bow and the medical officer is killed by a truck. The
K-19s first mission is to surface in the Arctic, test-fire an unarmed
intercontinental ballistic missile, and patrol the Atlantic within striking range of
New York City and
Washington, D.C. Vostrikov orders
K-19 to submerge past its maximum operational depth, then surface at full-speed to break through the Arctic pack-ice. Protesting the dangerous maneuver, Polenin storms off the bridge. The test missile launches successfully. A
reactor coolant pipe bursts. Control rods are inserted into the reactor, but the temperature rises; back-up coolant systems were not installed.
K-19 surfaces to contact fleet command but the long-range transmitter antenna cable is damaged. Engineers rig a makeshift coolant system, working in shifts to limit radiation exposure. The first team emerges vomiting and blistered. The second and third teams cool the reactor, but all suffer
radiation poisoning. With radiation levels rising, the submarine surfaces and most of the crew are ordered topside. Radtchenko balks after seeing the first team's injuries, and the
crew chief takes his place on the third team. A
Sikorsky H-34 helicopter from a nearby
United States Navy destroyer offers assistance, which Vostrikov rejects. The Soviet government grows concerned when the
K-19 ceases contact but is spotted near the destroyer. Hoping diesel submarines will be sent to tow the
K-19, Vostrikov orders a return to port. The repaired pipework leaks causing the reactor temperature to rise. Torpedo fuel ignites a fire. Initially ordering the fire suppression system activated—which would suffocate anyone in the area—Vostrikov is talked down by Polenin, who personally assists the fire crew. Two officers mutiny against Vostrikov and Radtchenko enters the reactor alone to attempt repairs. Polenin deceives the mutineers into handing over their weapons, arrests them, and frees Vostrikov. Unaware of Radtchenko, Vostrikov, at Polenin's behest, announces his plan to dive and attempt another repair, fearing an overheating reactor could set off their warheads and incite nuclear war. The crew responds positively, and
K-19 dives. Radtchenko's repairs are successful. Blinded and weakened by the radiation, he is dragged to safety by Vostrikov. A meltdown is prevented, but irradiated steam leaks throughout the submarine. A Soviet diesel submarine reaches
K-19, with orders to confine the crew aboard until a freighter can pick them up. Vostrikov instead orders an evacuation. Returning to the Soviet Union, Vostrikov is tried for endangering the mission and disobeying a direct order, but Polenin comes to his defense. In all, twenty-seven men died from radiation sickness. An epilogue reveals that Vostrikov was acquitted, but the
K-19 crew was sworn to secrecy and Vostrikov was never again given a command. In late 1989 after the
fall of the Berlin Wall, an aged Vostrikov meets Polenin and other survivors at a cemetery on the anniversary of their rescue. Vostrikov reveals that he nominated the deceased crewmen for the
Hero of the Soviet Union award, but was told the honor was reserved for combat veterans. Remarking "what good are honors from such people", Vostrikov toasts the survivors and those who sacrificed their lives. ==Cast==
