Plot

The author of the zero hit Nikolai Larionov works as a security guard of country villages. But one day his ex-wife Jeanne flies away on vacation and asks to look after their 14-year-old daughter Kasha, whom he has never seen. The teenager is not happy about the appearance of an infantile sloppy father and dreams of getting rid of him by placing him in good female hands. Unexpectedly, Cauchy's idea gives birth to a profitable business — an online dating agency. The new case will not only bring father and daughter closer together, but also help solve their financial problems: Kosha will negotiate with a blackmailer at school, and Nikolai will triumphantly return to show business.
