Alle lieben Peter

The 20-year-old musician Peter works alongside his studies in General Director Steiner's company. When he hires him to perform at his private party, Peter sees his big chance. Just one day before the festival, his widowed mother Sylvia meets the charming Bernd Werding. In order to impress him, she lies about her age and gets into trouble when Werding visits her at home. In order not to embarrass his mother, Peter disguises himself as a 14-year-old boy, which soon leads to complications, especially when Peter falls in love with Steiner's lovely daughter Kitty.
