Montmartre

Céleste, a 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 laundress, finds herself trapped by the man she loves.

Céleste does everything to save Rose, who is seriously ill. Meanwhile, Arsène is caught up in family conflicts, but a mysterious letter will disturb his certainties. After her daring act at the Rose Elephant, Celeste finds herself threatened and wonders if her sudden fame deserves the sacrifice of her newfound happiness.

Celeste must imagine an innovative act to save the Rose Elephant, which the minister threatened to close following the scandal. Arsène decides to go to America, but Augustine asks him for help finding Octave. Rose, for her part, takes risks by posing for an unknown artist from Montmartre despite her sister’s warnings.

Léon agrees that Céleste accompany him to Saint-Loup to investigate her father’s murder. Octave and Arsène, in search of funds for their electric motor project, organise a clandestine boxing match. Rose, who thought she knew Charles, discovers his true identity.

While she discovers inconsistencies about her father’s death, Céleste is convinced that it is a murder and not a suicide. Rose, caught up with her past, is unmasked by Charles’s mother. Arsène, helped by Octave, tries to break a speed record to save his project and find investors.

While questioning a former teacher from Saint Loup, Celeste discovers a new suspect who could be linked to her father’s murder. Victim of prejudice, Arsène is about to lose a major contract. Rose learns very good news and is eager to write to Charles to tell him.
