Three friends transform into superheroes at night when they put on their pajamas. During the school day a problem arises, and during the night the culprit is found by the PJ Masks and the problem gets solved by sharing ideas, recognizing strengths and weaknesses, and the ability of working together to get the problem solved. Everything is made right for the children, usually by the next day, thanks to the PJ Masks. Because nighttime (formerly ‘bedtime’) is the right time to fight crime.
