Loosely-based on
Allan Pease and
Barbara Pease's bestselling book, this comedy focuses on typical gender stereotypes that cause difficulties in relationships between men and women. When Jan wants to sleep with Melanie, student Katrin scratches his car's paint. Instead of arguing, he falls in love with her and they finally marry. Meanwhile, his boring roommate Rüdiger is romantically linked to Melanie. However, both couples must soon fight problems in their relationships.
