Marika is a cheerful girl who lives on the Danube aboard an old barge she inherited from her father. She works as a waitress in her aunt's inn, entertaining the guests with singing and dancing. Her greatest dream is to save enough money to repair the old barge and sail down the Danube. One day, she meets three young artists, Georg, Oskar, and Christoph, who all fall in love with her. Together, they put on an open-air revue and raise the necessary money. And with Georg, Marika is lucky in love.
