Phantom sees a Soviet submarine armed with nuclear missiles go missing in the Pacific during the height of the Cold War. On board, a battle-tested captain (Harris) and a rogue KGB agent (Duchovny) wage a life-and-death game of cat and mouse with a nuclear Armageddon hanging in the balance.

The Hunt for Red October meets Crimson Tide in this intense claustrophobic thriller about extraordinary men facing impossible choices!
