Much of the play is set in the locker room of a professional baseball team, and as such has an all-male cast that explores themes of homophobia, racism, class, and masculinity in sports.
Act I
Darren Lemming, a star mixed-race center fielder for the fictional Empires Major League Baseball team, comes out as gay. His friend and teammate Kippy Sunderstrom warns Darren that the team will feel uncomfortable about his sexual orientation, but is brushed off by Darren. As Kippy wonders why Darren chose that particular moment in time to come out, a flashback to a week earlier shows Darren having drinks with his best friend Davey Battle, a religious player on a rival team. Davey tells Darren that he should want his true nature known to the world. Later, Darren meets with his new accountant Mason Marzac, a gay man uninterested in baseball until Darren's coming out.
The Empires fall into a slump, prompting relief pitcher Shane Mungitt to be brought up from the minor leagues. Shane tells the team that as a child, he was raised in orphanages after his father killed his mother and then himself in a murder-suicide. The team begins winning games again, but in a television interview, Mungitt expresses his discomfort with "colored people" on the team, and that he has to shower every night with a "faggot."
Act II
Shane is suspended due to the interview, causing the team to fall back into its slump. He writes an apology letter that is leaked to the public, which combined with the details about his tragic childhood, causes public sympathy to shift in his favor. Shane returns to the team, despite Darren's threat to retire in protest. In the locker room showers, Darren derides Shane for his racism and homophobia, and mockingly kisses him. In the game, Shane is sent to pitch against Davey Battle; the ball hits Davey's head, killing him.
Act III
In a flashback to Darren and Davey's final encounter, Davey angrily accuses Darren of using his straight-and-narrow public reputation to conceal his sexuality. Shane is permanently suspended from major league baseball, and arrested for questioning after players say they heard him muttering about wanting to "kill someone" before the game. He refuses to speak to the police, stating that he will only talk to Kippy. Kippy is joined by Darren, and as Kippy attempts to determine whether the pitch that killed Davey was intentional, Shane discloses that the apology letter was written by Kippy on Shane's behalf.
In narration, Kippy states to the audience that the Empires went on to win the World Series, and no charges were ever filed against Shane. Kippy expresses to Darren his desire to again be friends, and Darren invites Mason to the end-of-season party.
