Mike (Vin Diesel), a struggling actor with tattooed biceps, auditions for a role as an Italian man. He delivers a profanity-laced anecdote in an Italian accent, about getting into a fight with another man in a restaurant for looking at his girlfriend. The anecdote ends with Mike saying that he discovered the man was a homosexual, so he beat up his girlfriend instead, and is surprised that she doesn't call him anymore.
The casting director expresses interest and has Mike speak Italian before telling him they'll get back to him. When the director asks Mike where the monologue came from, Mike says that it's a true story that happened to his friend. Outside, Mike calls his manager without an Italian accent. He complains about the monologue, which wasn't a true story, saying it was offensive and worries that it will keep him from getting the job. He wipes the fake tattoo off his arm and goes to his next audition.
At an audition for a commercial, Mike meets a black actor in the waiting room and the two of them talk about their careers. Mike tells the actor about the audition he just left, and again complains that he thought his monologue was offensive. The actor tells Mike he has just landed a role in an international commercial, but Mike says he doesn't want to do commercials because no great actors have had to do commercials. Before he can audition, the director tells Mike that his skin is "a little too light" and not to bother auditioning. He suggests Mike audition for a Spanish role in a soap opera instead.
Mike goes to another audition and reads a Cuban accent with a Hispanic actress. The two of them are portraying an argument, but when the actress launches into Spanish, Mike is unable to continue. As they're leaving the audition, the actress guesses correctly that Mike doesn't speak Spanish. She suggests Mike try out for a soap opera which is looking for Hispanic actors, but Mike says he doesn't want to do soaps because no great actors have ever done them.
Mike attends another audition, where the woman reading with him tells him that she really thinks he could do well. Mike does the reading with her in a heavy urban accent, but the casting directors cut the audition short, saying they're looking for more of a "Wesley type".
Mike moves on to another audition, where they are expecting him from a previous audition. The casting director sees on his resume that Mike can rap; Mike launches into a hip-hop routine. Afterwards, Mike sits down and does a monologue about being a young man watching his father on stage in a performance of Raisin in the Sun. During his father's performance, Mike came to believe that his father wanted him to be a great black actor. After his father died, Mike realized that his father wanted him to be a great actor full stop. When the monologue is finished, the casting director is impressed with Mike's performance, but admits that they are supposed to be casting an actor with long hair like dreadlocks. Mike leaves with a promise that they will contact him if they can cast him instead.
The film cuts to Mike sitting silently and angrily at a booth in a diner. He can overhear an actress talking to another man about how frustrated she is to be typecast as a blonde bimbo. When the waitress comes, the actress orders coffee that's "not too light, not too dark". Mike chuckles to himself and mouths the words "not too light, not too dark".
