The Four Adventurers Meet the Evil Professor

When four high school boys decide to spend their summer vacation touring the country in a horse-drawn carriage, they meet up with plenty of action and a whole series of exciting adventures. Their team spirit and a brave, old nag named Skippy carry the boys through one crisis after another. Tension mounts as Skippy is stolen and then later the hackney is taken by thieves. The boys have a brief encounter with the police, and a confrontation with a dark, sinister character by the name of Professor Pokanini. The climax occurs when the boys are caught in a frenzied brawl in a barn and are forced to fight for their lives.
