Sid Harkins is a lawnmower repairman who tells some wild stories—causing his wife and many of his friends to believe that fumes from cleaning solvent have affected his brain. Sid finds lying to be much more entertaining than repairing small engines—that is, until he meets tiny aliens from the planet Kranx. In appreciation for his help in repairing their small spacecraft, the Kranxians invite Sid for a visit to their planet.
But that's when his problems start. After so many tall tales, how does Sid convince anybody about his truly amazing adventure?
