1979 film by Vera Plívová-Šimková

A poor miner, Kuba Dařbuján, cares for his wife Markýtka and eleven children. When a newborn arrives, he seeks a godfather and, finding only Death fair to all, accepts a pact: as a doctor whom Death accompanies at the foot of a patient’s bed, he can heal; but if Death stands at the head, no cure is possible. Kuba eventually heals even a miserly brewer, violating the pact and imprisoning Death, leading to a world where no one can die and unforeseen chaos follows.
