In the future, humanity has stumbled upon a big problem that no one can cope with yet. Having populated many planets, everyone is afraid of the “dark ones” who kill suddenly and en masse, but no one has seen these creatures. A white-haired beauty ends up in one of the colonies on a huge planet. After checks, they begin to suspect her of belonging to the “dark” and send her further for a full body scan. The heroine herself is sure that this is a mistake. In the laboratory, the unusual properties of her body are revealed, but this remains a secret between her and the doctor. They enter into an agreement between themselves, for the benefit of both parties. The man wants to further study the properties of her body, and in return he will allow her to stay in the laboratory and will not tell anyone the truth of the examination. The heroine wants to find her parents, who are also being held in one of the colonies, and fly away from the planet. With each new step towards the goal, he learns more and more facts about the doctor, the laboratory and Mr. Wublans, who is the head of the entire north of the planet.
