Actress Lola Lácová will become a new addition to the Stone Theater, which is preparing for the premiere of a new operetta, in which Lola, as the main star, will play the main role. Her husband Ludvík is tired of their marriage, and in order to provide some compromising information about his wife for the planned divorce, he goes to the theater disguised. There, however, he finds out that his director does not treat Lola honestly, as he has accepted another actress to alternate Lola's role. Because he does not like such unfair treatment, he begins to pretend to be a mysterious Phantom of the Operetta (referring to the Paris Phantom of the Opera) and begins to create a mess in the theater that the management of the stage cannot cope with.
