800,000 Soviets and 400,000 Germans died in less than three months in Stalingrad, a vast field of ruins after the battle. Hitler wants the city that bears the name of his enemy.

Snipers and urban guerillas respond to the offensives of Paulus. Meanwhile, the Red Army is secretly organizing Operation Uranus. In November 1942, Russians and Germans were exhausted. The latter consider their enemies as rats. But the heroism and cunning of the Soviets, which stand in their way, proved decisive in a battle that changed the course of history.
