Watch VoirFilms. Little Péťa visits his grandfather in the Krkonoše Mountains, where a swarm of bees settles on a tree. When Péťa disturbs it, the entire swarm attacks him, leaving him in a deep coma. Ordinary treatments fail, so Dr. Vrba insists on a beekeeper’s blood transfusion. Grandpa’s blood type doesn’t match, prompting a frantic search—ambulances, authorities, even foreign donors—to find a suitable beekeeper. After multiple transfusions from various volunteers, Péťa shows signs of recovery. With dawn breaking, hope returns as he awakens.
