When 18-year-old Regan accidentally kills her father, she discovers some startling truths. First, she has the power of mind control. Second, she must use it for evil or else suffer one of two fates: insanity or death. Her solution is vigilante justice. To atone for her sins, she vows to protect her classmates from The Three Musketcheers, a vicious gang of cheerleaders who use lies, brute force, and blackmail as weapons in their quest to dominate the school. Unfortunately, every time Regan uses her gift, it develops a persona of its own-one she has trouble controlling-leaving her to question whether she can save them without destroying herself.
