A code, Tucker soon learns, that's coveted the world over: a time-sensitive code known as the Ultimate Encryption, capable of launching enough nuclear missiles to blow the world's superpowers off the map.

Sensing the value of his secrets, the CIA accuses him of murder, and within hours is in hot pursuit. On top of this, Tucker must elude the Sicilian Mafia to locate his patron's beautiful daughter and take her underground.

A ruthless psychopath pierces their disguise -- Vlad Jarrko, a bitter enemy from Tucker's CIA days. When Jarrko spirits Monika to a refugee camp in desolate North Korea, Tucker knows he must resume his bloodfeud -- and find Monica before she surrenders to her abductor's unspeakable tortures.
