Soviet feature film for children, filmed at the Mosfilm studio in 1974, directed by Eduard Gavrilov. A screen adaptation of the story "Kysh, Two Portfolios and a Whole Week" by Yuz Aleshkovsky. The heroes of the film are first-graders Snezhana Sokolova and Alyosha Seroglazov, who on the very first day of visiting school received the nickname "Two Portfolios" because of the joke of Rudik Baryshkin, who measured the student's height in an original way, as well as a small puppy Kysh, who, as it turned out, needed to be protected and raised to leave home forever.—seventhriotontheship
