Hallo Janine is a 1939 German musical film starring Marika Rökk as Janine, a gifted French ballet and tap dancer who dreams of a musical career in Paris. To achieve her ambition, Janine sets out to get revenge on Count René, who stood up her best friend Charlotte, by making him fall in love with her and then rejecting him. The plot involves mistaken identities at an evening function, as Janine doesn't realize that the man she believes is Count René is actually a composer and pianist named Pierre Tarin, who is also in disguise.
