Aurore Beauréal, an aspiring weather girl, loses a competition to be the weather forecaster for a kids' TV channel. Mad over the seemingly unfair results, the villain Hawk Moth uses an "akuma", an evil butterfly, to "akumatize" her, using her negative emotions to turn her into a weather-controlling villain, "Stormy Weather". With the help of their magical "kwami" creatures, Tikki and Plagg, teenagers Marinette Dupain-Cheng and Adrien Agreste use their ladybug and black cat-themed jewels, the Miraculouses, to turn into their superhero personas, "Ladybug" and "Cat Noir". Together, they defeat Stormy, but remain oblivious to each other's secret identities.
