A child called Max plays around his home making "mischief" in a wolf costume one evening. As punishment, his mother sends him to bed without supper. In his room, a mysterious, wild forest and sea grows out of his imagination, and Max sails to the land of the Wild Things. The Wild Things are fearsome-looking monsters, but Max proves to be the fiercest, conquering them by "staring into all their yellow eyes without blinking once", and he is made "the king of all wild things", dancing with the monsters in a "wild rumpus". However, he soon finds himself lonely and homesick and returns home to his bedroom where he finds his supper waiting for him, still hot.
