In the kindergarten, where five-year-old Masha went, they declared quarantine. All adults are busy with work: both parents and grandparents, and even great-grandmother and great-grandfather. Therefore, Masha will have to wait until her parents come home from work with relatives, friends, colleagues and casual acquaintances, learning a lot about a variety of people - an aged circus cashier living among pets, a young dressmaker who is on a diet of water and wheat grains, academicians , writers, students-janitors and many others.
