Clara Nightingale, the famous singer, is in France to film the music video for her new song Miraculous in tribute to Ladybug and Cat Noir. Marinette is overexcited; however, Adrien is worried because he has been chosen to take part in Clara's video as Cat Noir in a duplicate costume, which might expose his identity. At the audition, after Marinette saves her from falling (purposely to find the perfect girl to play Ladybug in the video), Clara decides to cast her as Ladybug in the video. Marinette turns down the offer to protect her identity, but changes her mind when Clara is about to cast Chloé as Ladybug. As Marinette and Adrien are about to put on the duplicate Ladybug and Cat Noir masks, Chloé gets revenge for being excluded by having her father ban Clara from filming the video in Paris. Saddened, Clara succumbs to Hawk Moth's akuma and becomes Frightningale, a dancing and singing supervillain, who can color the people who dance and rhyme with pink aura by hitting them with a magical mike, while also turning them into magenta statues if they resist to sing or dance.
