Careful, people!

An alien inhabits the spineless professor of the Faculty of Philology, Semenov, whose ship has crashed. To his horror, the alien learns that humanity is burning oil, which was created by scientists from a more advanced civilization as a cure for all diseases. The alien wants to warn his "fellow tribesmen" so that they can work together to rid the Earth of "human pests." However, he needs to repair his ship in a quiet location. However, he is constantly interrupted by Semenov's daughter Alyona, his ex-wife Katya, the dean, the UFO researcher, and his strong attraction to his colleague, Anna Mikhailovna.
