Surgeon Lemuel Gulliver (Kerwin Mathews) wants to explore the world before his marriage to Elizabeth (June Thorburn), despite her wishes to the contrary. He sets off on a ship, but is reunited with Elizabeth when he discovers she's hidden aboard. Their reunion doesn't last long, however. A storm leads Gulliver to a strange land inhabited by tiny people called Lilliputians. His journey then takes him to a rival land called Blefuscu, and finally to a land of giants named Brobdingnag.
