Skyscraper

She wakes up in a dark room with no door, no windows, and no idea who she is. The only clue as to how she can get out is a rope and crack in the ceiling. Of course she soon find herself falling to her doom. After being saved by a boy whose obviously a natural leader, she is united with 5 other people who are all missing their memories. The group finds themselves stuck in the basement of a building with only an elevator and the words "Welcome to Hell" written in what can only be blood. The 6 teens have to face battling their worst nightmares in order to make it to the top. Violet, as she is soon named, only worries that what's at the top may be scarier than the dangers they're already facing.
