Oliva (Jan Werich), the seer in a small village, tells a class of schoolchildren and their teacher, Robert (Vlastimil Brodský), of a mysterious acrobat and her cat, Mokol. The cat wears sunglasses that, when removed, reveal the true character and feelings of the people around her. Later a traveling circus arrives in the town featuring Mokul the cat, the acrobat and a magician who's a dead ringer for Oliva. The cat's powers delight the children but cause anxiety among the adults.
