Chéri-Bibi, a daring magician and master of escape acts, is celebrated throughout Paris, captivating audiences with his Houdini-like talents. Despite his fame, he faces skepticism from certain members of the aristocracy, who dismiss him as a fraud. Among these individuals is C. Aubrey Smith, portraying Bourrelier, a nobleman with a vendetta against Bibi. Crucially, Bourrelier’s daughter, Leila Hyams, Cecile, is deeply in love with Bibi, and their affection blooms despite her being engaged to the proud Marquis Ian Keith.
The story reaches a boiling point at a glamorous party, where an intense argument erupts between Bibi and Bourrelier over Cecile's affection. The confrontation ends with Bourrelier commanding Bibi to stay away from his daughter. Moments later, tragedy strikes—Bourrelier is found dead. The circumstances lead to Bibi’s arrest, and he is imprisoned, although his daring spirit doesn't wane. Four years later, he manages to escape from jail, relentless in his pursuit of truth and justice.
While hiding at a friend’s home, Herman, played by [Jean Hersholt], Bibi overhears a sinister revelation: Bourrelier’s murder was committed by the Marquis, who feared losing his inheritance to Cecile. Determined to bring the truth to light, Bibi goes to confront the Marquis, but finds him gravely ill with the flu. The Marquis confesses to the crime, with the help of his lover Vera, portrayed by [Natalie Moorhead], but dies before Bibi can produce a witness. Fearing wrongful punishment for another murder, Bibi secretly takes the Marquis’s body and seeks help from a clever doctor, Dr. Gorin, who uses plastic surgery to alter Bibi’s appearance, transforming him into the Marquis himself.
Reemerging publicly as the Marquis, Bibi spins a convincing tale that he suffered a head injury, which erased his memory, and that Bibi himself had died. During this time, Cecile, still heartbroken, had married the Marquis but remained deeply unhappy, secretly longing for Bibi. The truth eventually surfaces when Bibi, now living under his new guise, reveals his identity, leading to an emotional reunion with Cecile. Their happiness, however, is short-lived, as Detective Costaud, performed by [Lewis Stone], suspects that something is amiss.
Costaud demands to fingerprint the "Marquis" to confirm his suspicions. The fingerprints match Bibi’s, leading to his arrest once more. Bibi escapes from custody and confronts Vera, demanding she reveal everything. Her silence is broken when she admits her involvement, implicating herself in the process. This confession exposes the fake escape plan, which Costaud had been monitoring. Vera is subsequently arrested, and Bibi and Cecile are finally free to pursue their lives together, unburdened by the shadows of intrigue and deception.
Throughout the film, themes of love, treachery, and clever deception intertwine, illustrating a story of resilience and ultimate justice. The narrative showcases Bibi's extraordinary talent, both as an illusionist and a man willing to go to great lengths for truth and love, emphasizing that even in the darkest moments, cleverness and integrity can prevail.
