End of 1942. In Stalingrad, the army of Paulus is surrounded. The headquarters of the Supreme High Command planned Operation Big Saturn to encircle the entire Wehrmacht group in the North Caucasus. But Zhukov convinced Stalin that the operation was not feasible. "Big Saturn" did not take place. The implementation of the plan became possible when two consciousnesses merged in one head: our contemporary, Colonel-tanker Balyazin, who died near Debaltseve in 2015, and Colonel Brezhnev, wounded near Tuapse in 1942. Will the adventurous raid of just one tank brigade be able to change the balance of power in the North Caucasus? Will Comrade Brezhnev actually be able to earn the highest military award of the Soviet Union?
