Alan (Jared Harris) is a schoolteacher in London who also moonlights as a jazz disc jockey for a hospital PA system. One night after work, he goes to a bar and sees Beatrice (Asia Argento) a beautiful woman who is arguing with two men. Alan is immediately captivated by Beatrice and begins to pursue her. What Alan doesn't know is that Beatrice is an infamous thief known to the police as "B. Monkey" (named for her ability to break into anything) and the men she was arguing with were Paul (Rupert Everett) and Bruno (Jonathan Rhys Meyers) a homosexual couple who are her partners in crime. When Alan becomes aware of Beatrice's secret, he tries to lead her into a safer and more honest way of life, even as she lures him into the thrilling existence he's been dreaming of.

Anita Gates of The New York Times had a mixed review of the film but thought highly of the actors:

The best part of B. Monkey is reveling in the dark side of Rupert Everett. The dissolute Rupert Everett. Rupert Everett, drinking and drugging, destroying his chiseled good looks and recklessly putting his life in danger... which is where the second-best part of B. Monkey comes in: Jared Harris, who is becoming one of the most fascinating actors around.^[6]

In October 2017, Michael Caton-Jones revealed that he had chosen Sophie Okonedo, to star. However, the producer, Harvey Weinstein, decided the actress wasn't "fuckable". Caton-Jones and Weinstein discussed the matter heatedly, and Caton-Jones said, "'Don't screw up the casting of this film because you want to get laid', whereupon he went mental." Weinstein then leaked to Variety that Caton-Jones had walked off the movie due to "creative differences". Argento, who replaced Okonedo, was one of three women who in 2017 were reported in The New Yorker to have been raped by Weinstein; she said that she submitted to Weinstein because, "I felt I had to, because I had the movie coming out and I didn't want to anger him."^[7]
