He has one option and one option only – stop the threat, or everyone will die. Avner Ehrlich, the Mossad’s “operator,” is inserted into Tehran, on a mission to eliminate Professor Hamdani, a senior Iranian nuclear scientist. His task becomes increasingly complicated, and Avner is called to abandon his mission and return to Tel Aviv. But, being Avner Ehrlich, he decides to ignore the command and stay on course. A violent battle develops in Hamdani’s home, in the center of Tehran. With Ehrlich’s gun pressed to his head, Hamdani’s son comes running in and hangs desperately onto his father. Ehrlich lowers his weapon and retreats into the darkness. In the debriefing at Mossad headquarters, Ehrlich takes responsibility for the failed mission and is suspended from his position. However, it isn’t long before he is summoned urgently back into action when it turns out that Hamdani is in Moscow with Colonel Rasputin, and together they have armed a stealth submarine with the “Czar’s Bomb” – the biggest nitrogen bomb in the world. The submarine is making its way to join the Russian military fleet in Syria, but its true assignment is to bring destruction to Tel Aviv. For Ehrlich, one option remains – stop the bomb, or everyone will go to hell.

Mossad Agent Avner Ehrlich is a serial rulebreaker, but whenever the need for a dangerous top-secret operation arises, he is the Israeli Mossad’s first pick. But what happens when the hunter becomes the hunted, and Ehrlich finds himself an enemy target? Avner Ehrlich stands before the most cunning enemy he has ever faced – an enemy with innovative and sophisticated methods, That conceal the danger within… Imad Akbariyah, a rising star in Al-Qaeda’s chain of command, recruits a fellow Palestinian doctor to perform surgeries on terrorist Shahids and implant their bodies with plastic explosives that allow them to move freely through any security check or device. Imad will never forget the day when his father was killed in front of his eyes by an Israeli commando officer. Years later, he seeks to avenge his father’s death at any cost and dreams of the day when he will finally get his revenge on the man responsible. As the violent chases intensify, a blood-soaked war is only a matter of time. The personal encounter between the two rivals is inevitable – and Ehrlich is fighting not only to prevent the killing of innocent lives, but to save his own.
