Dr. Janis Michaels is doing a fellowship in cardiology at a major medical center. She is in the emergency room at the same time a mysterious female child is receiving care there. It soon becomes apparent to everyone in the department that something is terrifyingly wrong. The child is violent beyond her apparent capacity, and Janis soon learns that this is no child at all. It is a creature that has survived for millenia. It is strong, and it is hungry. It wants blood and flesh. Human is its favorite, and it has found the perfect place to feed...a hospital. Janis discovers all of this, but no one believes her, not the police, not the Chief of Medicine who is her father, no one. She fears for her life, and the lives of others, but there is no retreat for her. The creature now knows her.
