20-year-old Gosha, born into a well-to-do Moscow family, is sitting in his fourth year of medical school, but he really wants to become a film director. One day he declares to his mother that he is quitting medical school and will go to film school. His mother is ready to let her son realise his dream, but only if he proves that he can live for at least three months without guaranteed financial support. As a result, adult life falls on the yesterday's teenager: he has to find a place to live and earn at least some money for subsistence.
Gosha gets a job as a courier in a delivery service, and he begins a completely different life, to which he turns out to be completely unfit for. But gradually Gosha begins to change, although he always gets into ridiculous and funny situations. It is among the couriers Gosha finds real friends and his great love. And then Gosha learns that his father, whom he thought was dead, is alive, famous, and knows nothing about his son, who now works as a simple courier.
