Stalingrad

Stalingrad was a city in Russia.

The Red Room
During the final years of the Sovjet Union in 1988, Stalingrad was the home of the foster family of Nastasha Romanoff and Katenka Timofey, when the city came under siege by a separatist movement. Natasha and Katenka survived the destruction of their home and hid in the basement and not much later they were found by Russian forces. One of their commanders recruited both girls into the Red Room Academy to become lethal assassins.
