After a family tragedy and a startling discovery, Elle will be forced to face down her greatest enemy: herself. Elle, the high school student with as many personalities as she has hair colors, finds herself trapped in her subconscious mind following a double psychological shock. That leaves her to navigate the hidden worlds of her various personalities in search of an escape route, while Blue--a sociable version of herself with a tendency to lie, cheat, and steal--takes full control over Elle's life in the real world. Her friends start to suspect something isn't right ... but can they find a way to free Elle from Blue's bonds?
