Identity Crisis

Luke Flynn discovers suddenly, alongside the rest of his classroom, that one of the other, young students in the class filled with five and six-year-olds had gone missing. Two weeks later, the girl returns, yet she's different, her personality having mysteriously flipped, though she has no recollection of how she'd previously acted. Luke, his classmates, the teachers and the parents are put under a lot of strain as they try to prevent the other children from going missing and having the same fate, though as a pattern unfolds, it's proved to be futile.
