The hero, rushing from one misfortune to another, is former accountant Řehoř Maršíček, who after a heart attack, out of fear of death, decides to live a calm, moderate life and follow the principles of a healthy lifestyle. Not to smoke, not to drink, to exercise and eat healthily. He takes up the position of an auditor of patients and hopes that he will have peace in his new job. Instead, he experiences one nervous breakdown after another. He gradually makes one good resolution after another. Řehoř falls into unhealthy food, alcohol and women. In addition, he gradually loses most of his life's certainties, including a roof over his head. The result is a second heart attack, after which the hero promises himself again that he will fix everything and live a healthy life.
