Adolf, the irresistible seducer of women, is fond of Janicka, a novice opera singer. The girl, however, prefers famous men and Adolf thus does not have a single chance with her. One day in a hospital, he meets a Greek partisan named Apostolek who impresses him with his spontaneity and ease in solving all problems, especially those with women. Adolf has an idea for a revenge. He makes Apostolek familiar with social manners, dresses him after the latest fashion and introduces him to Janicka as a Greek conductor. Janicka instantly falls in love with the made-up composer and Apostolek does no better.
