Terrified. Trapped. Hunted.  Amid a rainy night, a girl awakens in a dark room, lying in a puddle of a strange, lime fluid. Most of her memories have disappeared, causing her to forget her name and who she is. The room is made of cold, rigid stone and holds no exit. A small speaker attached to the wall shouts a deafening alarm as a red light soaks the room. Outside, the girl can faintly hear the agonizing screams of other people. She is given two options: she can either starve and waste away inside this foreign prison, or she can find a way out. When she does escape, however, she is met with the maze-like halls of a withering laboratory. Yet, as she tries to flee this monstrous building, she is forced to discover the hideous truth within Sunrise Laboratories.
