It's 1945. The Reichstag fell. Parts of the army of the Soviet Union are slowly demobilized. In the Soviet Union, bandits and thieves disguise themselves as a soldier who has returned from the war. Police officers are actively fighting this phenomenon. You are a former officer of the Red Army. You entered the (Moscow criminal investigation department) MUR as an investigator, but first you are assigned as an assistant to an experienced investigator, Galina Zhiglova. (Thanks to dould for the inspiration.)

Uh oh. Looks like you've been caught crossing the border...
