Parisian nightclub owner Simone Pistache is known for her performances of the can-can, a provocative dance recently outlawed for being immoral. Though her dancing delights patrons to no end, it also attracts the ire of the self-righteous Judge Philippe Forrestier, who aims to punish her. The judge hatches a plot to photograph Simone in the act and ends up falling for her -- much to the chagrin of her boyfriend, handsome lawyer François Durnais .
