While changing back into his Clark Kent identity, Superman is observed by a man on the street. To prevent the discovery of his secret identity, Superman alters his appearance with a mustache and altered glasses. He is then seen by a schoolboy who mistakes him for a substitute teacher named Cranston.

Superman must carry on the charade because the man is watching him. He takes a job as a substitute and is assigned a class to teach. The class tries to play pranks on him, but using his powers he outmanuevers them. Finally, he surprises the class by revealing that he is Superman.
