Cuba Drobbyan (Jiri Sovak) is a poor cavalier who has a good wife (Bela Jurdova) and eleven children. When it comes to the twelfth, Cuba decides to go into the world and get a good godfather for him. Meanwhile, the old man meets Bohas Zahorsky, but he does not want to be a godfather, because he is not equally equitable to all people, he rejects the devil (Otakar Brousek), eventually meets the Deathwalker (Vaclav Lohnisky) whom he chooses because he belongs to all people just equitable. The Deathwoman makes a treaty with Cuba and gives him a special gift: When Cuba sees him with a sick person at his head, the person dies if he stands at his feet, the healer heals. Cuba tries it a few times, and the Death Gift works. Cuba will gradually become a respected and popular folk healer.The rich and fat brewery brewer Pandrhola (Rudolf Hrusinsky), who has always refused to help and make fun of Kuba and all the local poor miners, is the counterpart of the poor cavalier. Even one day it will get sick. He calls Cuba, but he first refuses because Deathwoman stands in the bed's heads. In the end, however, Cuba is allowed to cope with Pandhra and treats it despite the fact that it breaks the deal with the Death Eater - let the bed with Pandrhola turn around so that the Deathwoman, standing at the head, stands at his feet. But Pandrhola lets Smrtak be trapped in a brewery barrel, making it impossible for anything alive to die. This will cause great confusion and upheaval on the ground. Eventually, Death Knight comes out of the barrel, Pandrhol sets off with his deadly scythe, and Kuba definitively removes his gift.
