Seven-year-old Julian, his younger brother Huey, and his best friend Gloria have solved a lot of crimes in their time, everything from rescuing a dog stuck in a hot car to saving a toddler from drowning. But now they're on their most important case ever--solving a bank robbery and collecting the $25,000 reward. However, the trio's attempts at crimebusting don't go quite as they hoped, and they soon find themselves in trouble with the law.
