Set during the pandemic, the story unfolds in the family home of two women, a mother and her adult daughter. In one part of the house is the mother's music school, which she runs online. She is a piano teacher, a strong and organised woman who only has contact with her students, and therefore has an endless sea of children around her. The other part of the building houses the daughter's painting studio. The two worlds rarely come into contact with one another, constituting a metaphor for human loneliness. Ultimately, however, the protagonists are brought together by the story of the death of Katya, the daughter of their friend Inna.
