Céleste, cancan dancer in a cabaret in Montmartre, has only one obsession: to find her brother and sister from whom she was separated when their father was killed before their eyes. At the same time, Arsène, a talented engineer, has to face an arranged marriage, while Rose, a young whiter, finds herself trapped by the man she loves.

Celeste must imagine an innovative number to save the Rose Elephant, threatened with closure by the minister following the scandal. Arsène decided to go to America, but Augustine asked for her help to find Octave. Rose, meanwhile, takes risks by posing for an unknown artist from Montmartre despite the warnings of her sister.
