Oleg Semyonovich Mandrykin is a doctor, which means he promised Hippocrates to treat even those who are not paying cash, but are covered by insurance, in difficult times. He is hit by a courier, Dima, at the entrance to his building. Now the culprit of the accident will have to go on calls, and a real doctor will direct him by phone. But everything goes wrong from the very first patient. Dima immerses himself in the profession so deeply that Oleg Semyonovich can only dream of one thing - for this day to end as soon as possible.
