- Plot: The brother and sister Zuzana (Dagmar Havlová) and Petr (Jirí Lábus) are quite a notorious couple. They are fond of preparing people unpleasant surprises and are amusing by it. They dress a figure in a shop-window after a man standing at the pavement. The resemblance of the figure and a living man, whose name is Zezulka, is so striking, that they decide to take a figure, which they call Ronald, to a trip with Karel (Ludek Sobota), Zuzana's suitor.
