Lucy travels to a nearby hospital to remove the leaking container of drugs from her abdomen. The bag of drugs is successfully removed, and Lucy realizes that she requires the bags inside the other three drug mules in order to continue expanding her neural capacity and that the process of rapid cell growth the drug is stimulating will eventually kill her. Returning to Mr. Jang’s hotel, Lucy assaults him and telepathically extracts the locations of all three drug mules from his mind.
At her shared apartment, in which she had resided with an actor friend, Lucy starts a research about her condition and connected scientific material in order to find experienced and trustworthy support. She contacts a well-known scientist and doctor, Professor Norman, whose research may be the key to saving her. After Lucy speaks with the professor and provides proof of her developed abilities, she flies to Paris and contacts a local policeman, Del Rio, to help her find the remaining three packets of the drug. Her powers continue to grow, leaving her able to mentally disable an entire police force and the men who made her a drug mule. Lucy recovers the drug and must hurry to meet the doctor, with whom she agrees to share everything she now knows, once each cell in her body is controlled. Mr. Jang and his henchmen also want the drug and a gunfight ensues with the French police.
