Eleven-year-old Freddy has a worm on his shoulder. One that looks like a toy. No one, except Freddy, can see it, which is why everyone thinks he’s crazy when he talks to it, including Ira from the class above him. She is strange herself because she doesn’t talk to kids. When tests are destroyed at their school, the chubby Mr. Schulze-Kiefer, their therapist, has an idea. Can Freddy and Ira solve the case together and maybe even become friends?.
