Maksim Nesterenko is an actor who plays cops in different TV shows. His roles are always secondary, so he accepts any offer he can get just to earn at least something, and he knows this is all he has. Maksim’s private life is not good either. He has recently divorced his wife Marina, and his girlfriend, a rising star Snizhana, cheats him with his best friend. On top of all that Maks has recently lost a lot of money to a «serious man» Ihor Baloga and now he owes him. Baloga promises Maksim to forgive his debt if he does him a favor: Maksim has to deliver a case to the town of Kamensk.
Maksim agrees. On his way to Kamensk, he has an accident. A policeman Lemeshov, who happened to be around, saves him. However, Lemeshov himself dies when Maksim’s car explodes. It happens that Maksim and Lemeshov are confused since they look alike, and besides, the cop was on his way to another town to take up a new work, and nobody knows him there.
Hiding from Baloga, Maksim «temporarily» becomes a cop. On his first day at the new job he accidently solves a crime, and from now on he has a reputation of a great cop. In investigations, Maksim actively uses the experience he has from the shows he used to participate in. It annoys some of his colleagues and amuses the others. Maksim also gains an influential enemy (Inga Zhorina, «the mistress of the town”, with whom he slept at the beginning of his police career and who is not going to let him go that easy) and finds true love — a policewoman Ira Litvinovich .
Meanwhile, Maksim accidently finds out that real Alexei Lemeshev’s car had a damaged brake hose. Someone was planning to kill Lemeshov and now they are after Maksim…
