Steven and his best friend Russell are back! When Russell's dog, Rodney Rodent, jumps into a mural to chase a demonic-looking gnome and disappears, the Flint Future Detectives are on the case. With the secret password (Bow-wow-wow yippee yo yippee yay!) Steven, Richelle, and Russell enter the mural too, only to find the mysterious Mr. Chickee on the other side. To find a way out, the detectives must complete a mission—finding Rodney Rodent. And that means they're in some wild adventure!
