Persons Unknown Season 1 Episode 12 And Then There Was One
The abductees find six body bags in the bank vault. They “do the math” and realize that six of them are going to die. Joe explains that they will kill each other off.
Meanwhile, Mark and Kat trace the Program to the Mansfield Institute—officially a scientific, educational, and charitable nonprofit group. When they travel to the Manfield Institute’s headquarters and make a commotion, the Director notes that one has gotten so close before.
Back in the town, the abductees start killing each other. When the Program believes that everyone but Joe is dead, they place them in body bags and ship them out of the town. Once safely out of the town, the killings are revealed to have been an elaborate hoax. Everyone comes out of the body bags and suffocate the driver. The van then flips over a hill. The show ends with Joe talking to the program director.
