Marinette and Adrien are sweet innocent cinnamon rolls by day but by night they transform into Ladybug and Cat Noir who fight crime. Every mission is the same routine. Hawkmoth sends an akuma to someone that's sad or mad and then they turn into a supervillain and it's up to Ladybug and Cat Noir to de evilize the villain and all is well again. It won't be as well if everyone finds out who's behind the mask and what they're capable of.
