Bartholomew Collins (Tommy Rettig) has only one enemy in the whole world, his piano teacher Dr. Terwilliker (Hans Conried). Dr. T has a sadistic mad plan to force 500 young boys to practice at his magnificent piano 24 hours a day, 7 days a week. Bart is the only hope to save these poor boys from enslavement. The movie features the only piano academy ever known to be equipped with cells and surrounded by an electric fence! The screenplay, fantastic sets, and even song lyrics were provided by Dr. Seuss.
