Four friends live in the same courtyard of the capital's multi-storey building. Besides purely male interests, they are united by an important theme — the upbringing of children. One of the heroes is just preparing to become a father, the other raises a 7-year-old son, and the third — a son and two daughters of different ages. The heroes are madly in love with their kids, proud of their success and are actively involved in their upbringing. Only sometimes fathers forget that they have already grown up. And they have a fourth friend — an avid bachelor and lover who categorically does not want to have children.
