In the movie "Lucy," directed by Luc Besson, the character Lucy gains extraordinary cognitive abilities after a drug is introduced into her system. The film suggests a connection between her evolution and the development of human consciousness. However, it does not imply that Lucy is the first human. Instead, it uses the name "Lucy" as a reference to the famous fossilized hominin, Australopithecus afarensis, discovered in Ethiopia, which is often considered an early ancestor of modern humans. The film's narrative explores themes of evolution and potential.

At the end of the movie "Lucy," the character Lucy, portrayed by Scarlett Johansson, transcends her human form after unlocking the full potential of her brain. As she gains immense knowledge and power, she becomes more of a cosmic entity than a physical being. When she disappears, it symbolizes her transformation into a higher state of existence, representing the idea of evolution and the limitless potential of the human mind. Her final message to the world is encapsulated in her last words to the scientist, "I am everywhere," indicating her omnipresence.

In slang, "Lucy" often refers to "Lucifer," which can denote a rebellious or devil-may-care attitude. Additionally, "Lucy" can be a colloquial term for a psychedelic drug, especially LSD, due to its association with vibrant, mind-altering experiences. In the context of the movie "Lucy," the title character gains extraordinary cognitive abilities, which can metaphorically connect to themes of expanded consciousness often explored in drug culture. However, the film primarily focuses on the concept of unlocking the full potential of the human brain.

In the movie "Lucy," the drug is called CPH4. It is a synthetic substance that significantly enhances brain capacity and cognitive abilities when absorbed by the protagonist, Lucy, played by Scarlett Johansson. The drug is initially smuggled in her body, leading to her experiencing extraordinary mental and physical capabilities as she gains access to more than 10% of her brain, a central theme of the film.
