Tanz auf dem Vulkan.

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.
