Meet Maddy, Gus and Austin: three kids on a mission. They're three close friends with special talents: a champion rock climber, a computer genius and a mechanical whiz specializing in go-carts. Their task: to scale the heights and crack a high-tech bank vault to save an ailing Dad -- just in time to finish their homework. Their plan is foolproof, their methods ingenious. And they're not even old enough to drive.
