When a measles epidemic forces the temporary closing of a child care center, the son of a film star is mistakenly delivered to a touring musician. The film features an early performance by Audrey Hepburn playing a spoiled actress. Most Hepburn biographies indicate that it was during the filming of this film that Hepburn was first discovered by the playwright Colette and chosen for the lead role in the play Gigi, which would lead to Hepburn launching her acting career in Hollywood.
