Anna Sterkhova was going on vacation. And nothing that the sea is still cold - but it will finally meet with its beloved Nikolai... But the vacation had to be postponed for an urgent business trip: Colonel Saveliev sent her to a small town of Urutin to investigate one old case.

And recently, the female remains were discovered near that place, and there was an occasion to open the case again...
