In the turbulent aftermath of a failed uprising, a young boy watches his father loaded onto a barge destined for doom—and a daring escape by a seasoned revolutionary changes everything. Loyalties are tested, friendships torn apart, and a hidden fight for freedom begins.

A covert assignment disguised as a summer guitar performance pits two former friends on opposite sides of a brewing conflict — one fighting for freedom, the other enforcing the state’s grip.

In the heat of the Spanish Civil War, a simple musical clock from Deyanov’s past resurfaces and entangles old wounds with a life-and-death intelligence war. Loyalties are blurred, enemies close in, and a vital archive becomes the pivot of a dangerous mission.

A critical message is set for delivery, protected by the visual code of "The Three Exclamation Points," but the simple signal hides a deadly trap. Under the intense watch of the state police, Deyanov must quickly identify a flaw in the plan and improvise a daring exchange.

A high-stakes rescuing operation takes place on a cross-country train, where Major Deyanov must secure the lives of Russian diplomats.
