Phantom

At the height of the Cold War, the world holds its breath when a Soviet submarine armed with nuclear missiles goes missing in the Pacific. On board the vessel, the battle-tested captain (Ed Harris) and a rogue KGB agent (David Duchovny) are waging a life-and-death game of cat and mouse. With enemy forces closing in and time running out, the captain fights to keep control with nuclear Armageddon hanging in the balance.
