The young quantum physicist Konstantin teaches at university and during summer vacation he goes to a university’s sea campus. Every day he teaches for a group of students, and at night he keeps order in he dormitory. Students prefer summer, girls and their own youth instead of physics. Like a fish out of the water, Konstantin perceives the surrounding reality through the prizm of physics and feels the opposition between the classical world and the quantum one. Both worlds don’t seem to fit in.
