Comedy series centered around the Young-gu character played by Shim Hyung-rae. Originally as a spin-off of the character from A Journey (1986), the movies focused more on the comedic aspects of Shim Hyung-rae's persona.
Dr. Kojubu, a wizard, creates an abominable monster with the intention of ruling the world with evil and sends the monster into the world. By chance, the ghosts invade the country house where Young-gu lives, and then enter the body of the sleeping ones and manipulate them.
