Gigi, a taxi driver, receives an anonymous phone call. A voice that Gigi does not recognize tells her that within the next two hours, she must drive Bart and Steve to a local jewelry store, where a robbery will take place. The voice states that should Gigi refuse to carry out these instructions there will be "serious consequences" for her husband and children. Gigi knows Bart and Steve quite well since, in the past, they had all been part of a gang that carried out jeweler’s store heists frequently. However, Gigi has decided to turn over a new leaf and wishes to break away from the gang: in fact, she has not been in touch with any of its members for at least six months. Gigi does not want to have anything to do with Bart and Steve because she knows that they are extremely violent.
When Bart and Steve arrive, Gigi feels she has no option but to accompany them because she fears for the safety of her family. Gigi drives the two men to the jewelry store, where they steal $150,000 worth of jewelry. During the robbery, a salesperson is shot and killed by Steve. Steve states that the salesperson called him a “stupid monkey with a gun” and laughed when Steve told him to hand over the jewelry. Steve is five feet four inches tall.
Gigi waits for Bart and Steve, even though she is out of their sight while they are inside the bank, and she ultimately drives them to safety. Gigi returns home and takes her husband and children to her parents' residence because she is frightened of what might happen next.
Bart later goes to a bar, where he meets Louisa, and starts drinking heavily with her. Bart and Louisa leave the bar together and go to Louisa’s apartment, where they consume more alcohol. Later that night, Bart starts to touch Louisa sexually. Louisa asks him to stop, but after waiting a few minutes, Bart starts to touch her again. Since she knows of Bart's membership in a gang, Louisa is terrified of what Bart might do; she stays silent while Bart proceeds to engage in further sexual contact. Fortunately, Bart falls asleep and Louisa manages to run from the apartment and call the police. Bart is later picked up by police and charged with sexual assault, at which time he confesses his involvement in the bank robbery.
