Mamu, Mrs. Johnson, and Bella are getting ready to watch a play. They walk in front of a stage and find some seats. Meanwhile, Oobi is wearing a wolf costume, and Uma has a hooded dress on. Oobi explains to the viewers that they're performing a musical version of Little Red Riding Hood. Grampu wishes the kids good luck and goes to find a seat by the stage. Kako appears dressed as Little Red's mother, followed by Angus, who is wearing a woodsman's costume. Maestru tells the actors that it's showtime, and they all rush behind the stage curtain.
As the kids get ready, an interview segment starts. It features preschoolers talking about their experiences at the theater. Afterwards, Grampu and the rest of the audience are shown waiting for the show to start. Grampu realizes he's the only male in the crowd and gets a bit nervous. The ladies flock around him and giggle. Soon, Maestru introduces the musical show and tells the visitors to turn their cell phones off.
The play starts with Little Red's mom (Kako) telling her daughter (Uma) to bring a picnic basket to her grandma. The mom tells Little Red not to talk with strangers. Little Red takes the picnic basket and walks into a dark forest. There, she meets a smooth-talking wolf. The wolf, played by Oobi, convinces Little Red to pick some flowers.
With Little Red distracted, the wolf starts a soliloquy. He explains that he'll pretend to be Little Red's grandma and try to eat her. The next scene shows the wolf in the grandma's bed. Little Red walks in, carrying the basket and the flowers from earlier. She notices that "grandma's" ears and nose are bigger than usual, and the wolf reveals himself. Little Red's real grandma, played by Kako, appears onscreen. The wolf tries to eat them both, but he's stopped by the woodsman, played by Angus.
The woodsman tells the wolf to leave, and he sadly walks away. The grandma feels bad for the wolf because he was hungry and just needed something to eat. Little Red gives the wolf some strawberries from her picnic basket, and the group wraps the show up together. They all bow. Grampu and the other audience members cheer and clap as the episode ends.
