Bobby (Quinn Lord) and his family are housing a French exchange student named Jean-Louis (Vincent Martella) for a year, but a chain of strange happenings make Bobby suspect that his French exchange student may be an alien. He tells him that they are a friendly species and are trying to save the human race from other aliens that are somewhere in the neighborhood incognito. They find out that the aliens are pretending to be cheese puffs. After Dad opens the door, the aliens flood in. Then, the aliens break a window and swallow up the family.
Note: This is Lord's second time in the show since "Fear Never Knocks."
