An employee of the funeral home Pleticha calls his superior. He overhears that he is supposed to buy a wedding gift and deliver it to his boss's relatives. He therefore sets off to the given address to organize the funeral. When the mistake is explained, Pleticha, in return for the entertainment, performs dances and songs of various nations for the wedding guests. One of the guests, grandfather Boleslav Hnipírdo, experienced a train collision near Vrňany on his way to Prague. Since he was not injured, he does not even want to ask for compensation. Pleticha takes advantage of this and goes to the railway headquarters with his leg bandaged. He pretends to be Hnipírdo and is questioned in detail about his journey. Thanks to his talkativeness, he reveals, among other things, that he jumped on a moving train, drove illegally, spat on the window and tore off the emergency brake...
