The day before their regiment is discharged, Pavel Shirokov and his comrades are invited by a girlfriend to visit the house of her friend's benefactor, influential businessman Roman Boldyrev. While Boldyrev is on holiday, the friends decide to throw a party at his home unaware that their actions will have serious consequences. On his return, Boldyrev finds his safe broken into and immediately suspects Pavel. He hires a gunman to kill him, but the gunman is murdered by a fellow gangster before he can complete the job. Boldyrev, however, thinks Pavel eliminated the gunman because he was unwilling to return the loot. Along with the money stolen from the safe, there was also a very important map with top-secret coded information, and Boldyrev will not rest until he gets it back.
