Eddie is a down-on-his-luck bar pianist who has just been fired from another job. Desperate for work, he finds a school looking for a leader for its hopelessly incompetent marching band. Somehow, Eddie has to whip these kids into shape in time for the big band competition. Can he get them to march without tripping over their own feet, let alone win the contest?

"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."
