A hopeless romantic learns a thing or two about relationships when he gets too close to a long-term couple.

Set 1,300 years after the events of How To Train Your Dragon, dragons are now just a legend to the modern world. When a geological anomaly opens up an immense, miles-deep fissure in the Earth’s surface, scientists from all over the world gather at a new research facility to study the mysterious phenomenon. Soon a group of misfit kids, brought to the site by their parents, uncover the truth about dragons and where they’ve been hiding -- a secret they must keep to themselves to protect what they’ve discovered.

By daylight, Marinette Dupain-Cheng and Adrien Agreste are ordinary teenagers. But unbeknownst to their family and friends, the two of them carry a huge secret...using the powers of magical creatures called Kwami, they transform into the superheroes Ladybug and Cat Noir! With a mission to protect the city of Paris from the evil Hawk Moth, the two of them must learn to cope with their new responsibilities, as well as ordinary troubles involving love, school, family, and friends. Most of all, they must learn to put their romantic feelings aside in order to perform their duty, unaware of each other's true identities.

With time, Marinette and Adrien ended up becoming friends. But the collège girl discovers that declaring her feelings for her friend is not so simple, in fact, it will be almost the opposite!
For Ladybug and Cat Noir, despite their new powers and teammates that they can call upon when the situation requires it, the fight with Hawk Moth becomes harder and harder. Their opponent is always stronger as long as he can call on Mayura, a villain who can create allies for the Akumatized, the supervillains.
More powers, more action, more villains, and more emotions! Season 3 will put Adrien and Marinette to the test: Will they be able to keep their secret and prevent their private life from interfering with their superhero adventures?
