The novel begins with 16-year-old Steve Harmon writing in his book awaiting his trial for murder. Musing on his short time in prison so far, he decides to record this upcoming experience in the form of a movie screenplay. Kathy O'Brien, Steve's lawyer, informs him of what will happen during the trial. At this stage, only two of the four accused – James King and Steve – will be tried, since the other two accused – Richard "Bobo" Evans and Osvaldo Cruz – have entered into a plea bargain. When the trial first begins, Steve flashes back to a movie he saw in his school's film of predictability.
The trial begins with the opening statements of the prosecutor Sandra Petrocelli, Miss O'Brien, and King's lawyer, Asa Briggs. Petrocelli labels the four accused men, including Steve, as "monsters." The lawyers call on several witnesses, including Salvatore Zinzi and Wendell Bolden, illicit cigarette traders, who admit to buying cigarettes that came from a drugstore robbery that led to the murder. The story of the trial is often broken up by a variety of flashbacks, including ones showing that King is only acquainted with Steve, that King had accused Steve of pulling the trigger during the robbery. Petrocelli calls as a witness Osvaldo Cruz, who is affiliated with the Diablos, a violent street gang. Cruz admits to participating in the crime only due to coercion by Bobo.
The novel depicts the themes of identity, race, peer pressure, dehumanization, crime, teenaged masculinity, and the relative or subjective nature of the truth.
