On the weekend, Artyom, Lena and Tolik are going to have a picnic, but Khrulev calls them and instructs them to investigate the theft of family jewels in the family of a businessman friend. Arriving with Mukhtar at a country mansion, the operatives inspect the office with a safe. Having found no extraneous traces, Tolik goes to play, and at the same time to talk with the children. And it turns out that mom and dad have been fighting for a long time and divorce is just around the corner… That's when the kids came up with the idea of how to reconcile their parents.

During a morning jog in the park, Artyom detains two juvenile delinquents — guys who robbed a passerby. Later it turns out how these two found potential victims, choosing an acquaintance for the role of "gunner".
