She's the spirit who haunts the old senior dorm, and this year is no exception. For Haley, the timing couldn't be worse. This month marks the one-year anniversary of the death of her ex-best friend, Taylor. When a disturbing video of Taylor surfaces, new questions about her death emerge. And it actually looks like Taylor was murdered. As Haley digs into what really happened last year, her search keeps bringing her back to the Winter Girl. Haley wants to believe ghosts aren't real, but the clues say otherwise. Now it's up to her to solve the mystery before history has a chance to repeat itself and another life is taken.
