Hermione Granger and Draco Malfoy are sent back to their First Year by a demon, and not only that, but they've switched places. Hermione is a Malfoy, and Draco is a Granger. At first they believe the past will simply repeat itself, but the demon has another idea. Draco and Hermione have to work together to escape from this sick game, but can they put aside their differences?
