This is how private detective Tanya Ivanova ended up! She has two things to do at the same time, and it is unknown which one is more difficult: firstly, she received an order to search for a missing girl. And, secondly, she was temporarily given a pupil - a cheeky ten-year-old boy, who immediately imagined himself as a young assistant detective and now sticks his nose where it doesn’t belong! But you can’t leave him alone, the child is too playful, and therefore Tatyana has to take him “on business,” where there is shooting, chases and fights... And all because Tatyana initially followed the wrong trail. But now she must get out of it so that her glory as a great detective does not fade in the eyes of a child...
