As Colonel Nutt is experimenting with explosives, a new janitor is joining his household. The inept janitor proceeds to make life difficult for the rest of staff. Meanwhile, a foreign agent arrives at the house in hopes of getting Col. Nutt's latest invention. The inventor throws him out, so the agent then employs a thug to get the formula. When police head to the Nutt home to start an investigation, a complicated fracas ensues.
