Due to a strike by armored truck drivers, Richie volunteers to transport a large sum of money to the bank for his father. Someone in disguise makes several attempts to steal the money, but Richie has a few tricks up his sleeve (or in his lunch kit).
Richie and his pals are trying to have fun, but Reggie keeps spoiling things by trying to one-up them. His chemistry set is bigger and better, his model planes have guns which shoot down Richie's, and his robot destroys their do-it-yourself train. But Richie finds a way to turn Reggie's equipment against him.
