Imprisoned for a crime he did not commit, Rudolf (Dolphy) attempts to escape many times--all unsuccessful. He realizes that he's in for the long haul and decides that his wife Sandra (Zsa Zsa Padilla) should remarry for the sake of their children, Melody (Jolina Magdangal) and Mark (Vandolph), who have been made to believe that he is already dead. Many years later, he's informed that the real culprit has been caught and that he will be released, but instead of being happy, he's sad that he can't return to his family. Finally he gets the idea to pretend to be a piano tuner so that he can visit his children.
