context: Edie Sedgwick (Sienna Miller) is a young heiress studying art in Cambridge, Massachusetts. She moves to New York City, where she is introduced to pop art painter and film-maker Andy Warhol (Guy Pearce). Intrigued by the beautiful socialite, he asks her to perform in one of his underground movies. Soon she is spending time with him at the Factory, his studio and also the hangout of a group of eccentrics, some of them drug addicts. Her status as Warhol superstar and success as a fashion model earn her popularity and international attention.
  Her Cambridge friend Syd introduces her to poet and singer Billy Quinn (Hayden Christensen), a character based on Bob Dylan. Andy becomes jealous, so Edie tries but fails to keep her love affair with Billy a secret. To reconcile them, she arranges a meeting. Although he agrees to be filmed by Andy, when Billy visits the studio he shows his contempt. As he is leaving, she tries once more to make peace, but Billy calls Andy a "bloodsucker" who will "kill" her. Seeing that she will stay, he kisses her forehead.
  As addiction takes its toll, Edie's relationship with Andy deteriorates. One night while in a drug-induced stupor, she falls asleep while smoking a cigarette and nearly dies in the ensuing fire. Vogue refuses to hire her; editor Diana Vreeland (Ileana Douglas) explaining that Edie is considered "vulgar". Interrupting a luncheon of Andy and his friends, she demands to be paid and accuses him of ruining her.
  When Syd sees her again, she has become a prostitute. In a taxi, he shows Edie, who is very depressed, a photo of herself when they were art students. He says that he fell in love with her then, and tells her that she can still be an artist. She says that she cannot bear her loneliness but interrupts him, asking the driver, "Can we go?" When the driver says that they are stuck in a traffic jam, she leaves the cab and runs frantically down the street. The scene changes to a hospital, years in the future. She tells an interviewer that she is overcoming her addiction and is glad to be home in Santa Barbara. The closing caption explain the last few years, her struggle to control drug abuse and her marriage to another patient, which ended in less than four months when she died of an overdose.
