By day, 6 year olds Catboy, Owlette and Gekko go to school like any other children. But that's only during the day ... Because at night, they put on their magical pyjamas representing their spirit animals, the cat, the owl and the lizard, and instead of going to bed, they transform into Super-Heroes and become the PJ Masks ! Catboy is nimble and lightning fast, Owlette can fly and see very far, and Gekko can climb any surface and has superhuman strength. Together, they can face any challenge. They truly are superheroes for the little ones. Their mission: thwart the bad guys’ evil plans and defend justice at all costs!
