A young front-line soldier Vladimir Sharapov, sent to serve in the criminal investigation department, gets acquainted with the head of the department - Gleb Zheglov and other members of the Moscow Criminal Investigations Department.

The capture of Fox is one of the tasks that the Mourovians must solve. Part of the events take place in the house where Fox brings to storage stolen things. This "transit point" becomes the place of an ambush. However, a carefully thought out plan is thwarted.

Sharapov begins an autonomous investigation of the Larisa Gruzdeva murder. Meanwhile, the Mourovians are developing a plan to capture Fox at the Astoria restaurant.

Events develop in the lair of the "Black Cat", where Sharapov gets, trying to get in touch with the bandits. Meanwhile, Zheglov, realizing that "the meeting place can not be changed", prepares the store for a special operation.
