The Eurovision Song Contest is an international song competition, organised annually by the European Broadcasting Union (EBU) and featuring participants representing primarily European countries. Each participating country submits an original song to be performed on live television and radio, transmitted to national broadcasters via the EBU's Eurovision and Euroradio networks, with competing countries then casting votes for the other countries' songs to determine the winner.

Dr. Oskar Sommer, a good-natured high school teacher, takes on a momentous task for the school janitor, also named Oskar Sommer: he is to play the role of the janitor's daughter's father for a few days. Since the real father has not been seen for 15 years and has pretended to be a teacher in his letters, the two Sommers promptly pick up the wrong person at the train station.
