In a plane flying over Russia, there are people of different nationalities. Between the Dagestani Hasan and the Russian Kolya, a conflict erupts on a national basis, in which both, not embarrassed in expressions, become personal. Despite the passangers' best efforts, the conflict quickly escalates into a fight. With great difficulty, the fighters manage to be pulled apart, but it soon turns out that the plane is out of order and will have to be put on the water in an emergency. Anxiety in the cabin quickly turns into panic, and now those who recently fought each other are faced with a situation in which their disagreements are worth absolutely nothing.

Based on real events, a short film-sketch about one day in the life of Professor Leonid Leonidovich Vasiliev and a psychedelic experiment on a Soviet student.
