Intimitäten (1948)

Peter Korff isn't a famous actor yet, but he is young, handsome, adventurous – and once again hopelessly in love. The object of his affection is named Erika and works as a model at the fashion salon "Yvette." Although the pretty young woman claims to be just as in love with Peter as he is with her, she's always up for a little fling behind his back.
