1956. By a special decree of the USSR’s top leadership, a top-secret underground military laboratory is established in Soviet Armenia.  Two young Armenians arrive from opposite ends of the world. From Russia comes Colonel Avakov, appointed commander of the facility and tasked with delivering results that could change the balance of power. From the United States comes Adikhanyan, a CIA operative dispatched to the Armenian SSR on a single mission: penetrate the lab and extract its most closely guarded secrets.  Inside, the rules are absolute. Every sound, every movement, every door that opens can trigger an irreversible chain of events.  Will Colonel Avakov complete his mandate—will he succeed in building a nuclear weapon? Can Adikhanyan, with his life on the line, obtain the information that could rewrite history?  In this espionage thriller with mystical undertones, the decisions that determine human destinies are made in silence—behind the laboratory’s heavy metal door.
