A woman who recently lost her daughter turns to private detective Tatyana Ivanova for help. She is sure that Irina was killed by her former lover, the son of a rich man, who wanted to return his gifts when he urgently needed money to pay off a gambling debt. However, Tatyana quickly finds out that the young rake had nothing to do with it: his dad, as usual, paid for him. In addition, Ira’s neighbor saw her alive after their last date. Why, then, is there such destruction in the girl’s apartment, and who is the owner of the tough guys hanging around in the yard during the robbery?
