A German soldier on leave in Berlin goes looking for his pen pal who he has never met called Gisela. He meets instead a woman with the same name and falls in love with her.

Paris, 1830: Jean-Gaspard Debureau performs on the stage and delights his audience with song, wit and charm. He is, however, very unpopular with King Charles X, who is the target of much of Debureau's scornful jests. That would be a somewhat tolerable situation if it weren't for the fact that Debureau has fallen for a countess, who happens to be the King's mistress.
