They All Do It.

Johannes is a shy and inexperienced young student at the music conservatory. He is a Mozart admirer and in love with his fellow student Elisabeth, who also seems interested in him. The smart and modern Herbert, called Pop, has dropped out of the conservatory and lives as a jazz musician and womanizer. He bets Johannes that he can sleep with Elisabeth before 8 p.m. that same day, since all girls are the same. He wins the bet, while Johannes consoles himself with Solvei, the girl who lives downstairs and works in a grocery store. In the end, Johannes and Elisabeth meet on the stairs. Can they still find each other?
