Max is creating havoc at home, so Mum sends him to bed without any supper. Then his bedroom changes into a forest and he gets into a boat and sails across the sea to an island inhabited by the Wild Things. Max proves that he is wilder and more fierce, so they crown him King. His first command is that the WILD RUPUS must begin. After that, Max is tired and decides to go home. When he gets there, his supper has been left for him. It's still hot.
