In Broomstown, where Robocar Poli's rescue headquarters is located, lives Peter, a mischievous troublemaker, in a happy family with his dad, mom, little sister Lucy, and pet dog Buddy. Peter, along with his best friend Johnny, the cool Cindy, and the timid model student Charlie, explores the town in search of fun games and exciting adventures. However, behind the children's joyful daily lives, the danger of safety accidents always lurks. Facing emergency situations and various disasters that occur at home, school, or playgrounds due to mistakes and carelessness, our superhero, "Roy!", intervenes to protect precious lives. After rescue operations, he conveys easy-to-understand and systematic safety rules, tailored to children's perspectives, to prevent accidents. Thanks to the brave Roy and the rescue team members, Broomstown is always full of life and peace!
