Nukes recovered from a sunken U.S. submarine have been planted in four largest cities of the world by a terrorist Jaffad Ben Zaydi. A code of fourteen numbers and a single phone call can trigger them any moment - this is the Apocalypse Code. An agent of the Russian FSB Darya infiltrates the terrorist organization and witnesses the killing of Jaffad, who at his last breath tells her that the code has been divided to three trusted persons. Jaffad’s partner, the “Executioner” is determined to find them and trigger the nukes, so is Darya to prevent it. They both begin their search for the code around the world, whereas one cannot harm another - they both have parts of it which the other doesn’t.
