Nino is a contestant in a game show called The Challenge, where he has to get Mr. Bourgeois to dance. Despite being invited, Marinette is grounded by her parents for missing too many classes at school, not knowing that she had been working as Ladybug. As Nino completes his challenge, the next contestant, a hypnotist named Simon Grimault, is given the challenge to hypnotize Adrien's father, Gabriel Agreste. However, Gabriel refuses to participate in the challenge, causing Simon to fail. Angry that he was not given the chance to at least try, Hawk Moth has Simon akumatized into Simon Says, an extravagant villain who can hypnotize people by throwing play cards at them. Simon invades the Agreste's mansion, while Adrien has to persuade his stubborn father. After the villain is defeated, Ladybug learns about Adrien's mother who had gone missing.
