Vesper follows the character of Emily Webb, a geeky girl that's more likely to stay at home and watch old horror films than go to parties. Unbeknownst to her, she's been sneaking out to go to parties and thrill seek when Emily thought she was asleep. She first takes notice of her nocturnal activities when one of her classmates that shares her name has been found murdered. Despite her attempts to prevent herself from going out, Emily's other self keeps going out and getting wilder with each passing night. This other Emily is not only wilder, but stronger and faster than her normal self.
