Hledá se táta! (1961)

It all starts when two men arrive at the asylum. Mr. Houdek, who goes to see little Honzik Slavata, the illegitimate child of his colleague, whom he wants to adopt, and young Standa Hurych, who takes up a position as a driver. The pretty nurse Magda mistakes Standa for his father and is angered by his reaction. However, when Mrs. Houdková insists that the adoption will not take place until the child's true father is known, Standa offers to help Magda track down the father. He immediately sets about the difficult task.
