Tom, Dick and Harry, a trio of college chums, spend their leisure time in framing up jokes upon each other. Dick and Tom have been reprimanded by the head of the institution for tardiness, so they buy an extra large alarm clock, in order to prevent and repetition of a trouble that may lead to their expulsion. In order to see them move three hours earlier than their scheduled time, Harry sets the alarm and lies abed, laughing as the other boys scramble into their clothes and rush hastily out into the wee hours of the morning to get breakfast that will not materialize for a long time. They soon determine that Harry is the responsible party for their early discomfiture and retaliate by sending him a letter from his sweetheart, enclosing an invitation to a masquerade ball and instructing him to dress as Mephistopheles. Harry takes the invitation in earnest and at the chosen hour and place finds himself face to face with the president of the college who emphatically disapproves of his devil's disguise. He beats a hasty retreat and on his way back to his room has a series of desperate and embarrassing experiences.
