before the arrest, Docent made him to dive into an ice-hole at the lake for some reason. Immediately, Sad Sack realises that the stolen helmet is hidden in the lake, and the trio sets off to the local boat station, where the real Docent finds them, armed with a knife. He orders Crosseyes to retrieve the helmet from an ice-hole, then takes it and leaves, forcing the gang to take care of the naked Crosseyes. At the same time, Professor Maltsev's daughter arrives at the country house to visit the so-called archeologists once again. Troshkin takes her car, rushes to the boat station and comes face to face with his criminal doppelganger. After a short fight, Crosseyes, Sad Sack and Vasiliy Alibabayevich knock out Docent and then Troshkin with an oar, and decide to turn them both in to the police, believing that two Docents will reduce their prison sentences much more than one. The police take both Docents away, and Professor Maltsev finally gets his precious helmet back. Then the police cars leave, while Crosseyes, Sad Sack and Vasiliy Alibabayevich are left standing there, not having a clue why the police have not taken them away as well. At that time, one of the cars stops and Troshkin comes out, this time without the toupee. Seeing this, the trio runs away in shock down the road (thinking that he has been "shaved clean" for prison and projecting that the same fate awaits them) while Troshkin chases after them to say goodbye.
