The police have been unable to catch a couple in love for a year now, who make daring raids on jewelry stores and each time take one of the most valuable items, lulling all witnesses with gas and leaving no traces. And finally, a tiny clue appeared: investigator Shura Andreeva suggests that the criminals are going on a two-day group excursion to Kaliningrad; of course, not to relax, their true goal is the Amber Museum. Shura's arguments did not convince the chief, he refuses to carry out the operation, and Shura, at his own peril and risk, goes on an excursion alone, under the guise of a simple tourist. More precisely, not alone, but with her beloved husband Yura, who does not even suspect that this trip is his wife's next task. In two days, Shura will have to find out which of the tourists who arrived separately is hiding a love affair and is going to rob the museum. Prevent crime and save your own marriage - that's the challenge for the weekend!
