The people of Eureka are being kidnapped and replaced by body-doubles one by one unless Allison, Fargo and Zane can figure out how to avoid capture and save their town.
- This episode is a reference to the cult classic movie "Invasion of the Body Snatchers" with an SF twist; the only difference is that the doubles are blank mannequins that were supposed to be used for bringing back Holly, but instead created evil versions of themselves. It was later discovered that these doubles are in fact the "Eureka Matrix" versions of themselves who became self-aware.
