The Sleeper was a subject in secret tests known as the "Sleeper Project", an experiment created by the CIA and a group of Hypnotherapists. She believes she serves the Goddess of sleep and death, who can only be appeased by the removal of the heart of a victim. However, she was being used by a CIA agent known as Remmy, to assassinate people who worked on the project in order to cover it up. |
