Young surgeon Oleg Samarin, nicknamed Samara, still works in the ambulance service. However, he is not exactly a doctor, but just a paramedic. Despite being a truly gifted healer, Oleg lacks the time and discipline to obtain a higher education and become a professional physician. Although there are doctors by chance and medics by calling, it is clear that Samarin belongs to the latter category. Together with his cheerful and eccentric colleague, driver Mikhalych, the hero helps people every day.
