An elderly man, a scientist, catches a thief red-handed in his own house. And he acts outside the box in this situation - he does not call the police. A conversation is started between the owner of the house and the “guest”, but he is interrupted by the arrival of journalists who were scheduled to meet, and the conversation with them only causes annoyance, bothering him with their “duty phrases” ... In addition, the unexpected arrival of his son and a showdown with him, escalated into a dispute on raised tones. All these events make it possible to catch all the facets of the relationship between people of different generations, especially between relatives and friends.
