The heroes of the film are students of a pedagogical university, those who, after a year or two, have to carry knowledge to schoolchildren, "to sow the rational, good, eternal." In the meantime, student practice. True, the practice is not quite ordinary, because for the first time students leave far from the walls of their own university, for the first time they meet with students in the classroom not in the presence of their teachers, those with whom life encounters them daily at the institute, but with those who have been working for more than a year at school.
