In a world run by the mob, street gangs, drug addicts, and corrupt cops, Lucy (Scarlett Johansson) is a woman living in Taipei, Taiwan who is forced to work as a drug mule for the mob. A drug implanted in her body inadvertently leaks into her system, which allows her to use more than the "normal" 10% of her brain's capacity, thus changing her into a superhuman.[8] As a result, she can absorb information instantaneously, is able to move objects with her mind, and can choose not to feel pain or other discomforts, in addition to other abilities.[5]
