Vasily Muravin, 50, a teacher at the Moscow Institute of Management, is experiencing a crisis. At work, the place of the head of the department is replaced by the more pragmatic, but limited person Valentin Romanovsky. At home, his wife Lida, who earns at work more than her husband, habitually reproaches him for indecision. It’s hard for Muravin to come to terms with his established attitude to himself, but he is most worried when his wife shows disrespect for his main hobby - playing the guitar. Once, unable to bear the bullying, Muravin suddenly leaves the family (wife and daughter) and from work.
