Mr. Chickee, the genial blind man in the neighborhood, gives 9-year-old Steven a mysterious bill with 15 zeros on it and the image of a familiar but startling face. Could it be a quadrillion dollar bill ? Could it be real? Well, Agent Fondoo of the U.S. Treasury Department and his team of Secret Government Agents are determined to get that money back! But Steven and his best friends, Russell and Zoopy the giant dog, are more than a match for the Feds. After all, Steven is the president of the Flint Future Detectives Club, and the inventor of fantastic spying and detecting equipment such as the Snoopeeze 9000!

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! As Steven says, "I second that emotion."
