Maddy, Gus and Austin are three kids on a top-secret mission! They’re close friends, each with special talents: a champion rock climber, a computer genius and a mechanical whiz specializing in high-speed go-carts. Their challenge: to crack a high-tech bank vault and pull off the biggest heist their homeroom has ever seen--all to save Maddy's ailing Dad! They may have a plan that’s foolproof, but they’re not even old enough to drive!
