Young programmer Kirill dreams of presenting his startup to influential businessman Oleg Potapov. But instead of a business meeting, he finds himself caught up in a dangerous and comical chase. Potapov and Katya escape their pursuers, and suddenly he mistakes Kirill for his old friend Sizy. Under a hail of bullets, Potapov literally drags Kirill into the car, and together they drive away from their pursuers.
During the chase, it turns out that Potapov, following a head injury, has suffered a rare form of amnesia: he perceives himself and the world around him as if it were the heyday of the 1990s. Potapov's deputy, Zharinov, has hired Professor Yeldantsev and event organizer Svidunov. Together, they conduct a therapeutic quest for the businessman using Yeldantsev's method, during which they completely reconstruct the events of his adventures in the 1990s, when bandits wanted to seize his business from Potapov and his accomplice, Sizy. Now they are about to plunge into a series of adventures.
