Musical feature directed by Roy Rowland and starring Peter Lind Hayes, Mary Healy and Hans Conried. Young Bart Collins (Tommy Rettig), much like any other kid, has a strong dislike for certain things. While many children may simply detest peas and the fact that they are forced to eat them, Bart utterly hates the fact that he is constantly made to practice playing the piano.

Even when his tyrranical tutor Dr. Terwilliker (Conried) is not snarling at him, Bart's mother is just as overbearing. His experience traumatises Bart so much in fact that he dreams of Dr. T taking him prisoner and forcing him to operate a colossal piano alongside hundreds of other children while his mother is under the vile doctor's spell. Bart encounters a friendly plumber working in the compound and together they conspire to stop Dr. T's scheme and escape.
