For years the Olmstead High Marching Band was out-of-tune, out-of-step and out-of-their-minds. But now they've got a new leader.

After several months of hard times, pianist Eddie Layton is offered the job of bandleader at Olmstead University. His first meeting is discouraging, as the young people are a happy group with very basic musical skills. But Eddie doesn't give up, he wants to motivate his students and his enthusiasm pays off. With the help of French teacher and band sponsor Miss Cooper and billionaire Elmo De Lavallard, who buys new instruments and brightly coloured uniforms, Eddie is proud to lead these musicians who play their hearts out for him.
