Petr Kratov is a former military surgeon, a luminary of medicine. A former respected member of society, a former exemplary family man. Now Petr works as a paramedic in an ambulance team, and lives in the house of his eldest son
Viktor - the head of the department for combating drug trafficking. Victor, out of a sense of filial duty, pulled his father out of the bottom, paid for treatment at a clinic for addiction, settled him in his place, and found a job for his father through friends.
In the ambulance, Kratov is half-jokingly called
Hippocrates - because of the rhyme with the surname and for his morbid commitment to the oath to help any patient in need of help.
A redistribution of the drug market is taking place in the city, and Kratov, against his will, is forced not only to help the leader of a criminal group, of which his youngest son is a member, but also to hide his affairs from his son, a policeman, who is determined to destroy this group.
