In a small town somewhere in South Dakota, a population of only about one thousand stands. When the teenagers of the town begin to go missing, they only assume a serial killer is at work, fearing for their lives. Though the odd part is that exactly twenty-four hours following each kidnapping, an unknown teenager appears that looks exactly like the original, claiming to be the missing one. Only few don't believe it, but when the IDs and documents begin to match up, they're at a loss of explanation. Once the odd teenagers' disappearances stop, they think the menace may have finally left. But when another disaster strikes the town, the population may have no other choice than to step up and face whatever power is at work, or suffer the consequences.
