According to producers, Race concerns "three attorneys, two black and one white, [who] are offered a chance to defend a white man charged with a crime against a black woman." Mamet elaborated on the plot in an interview with the New York Times. "In my play a firm made up of three lawyers, two black and one white, is offered the chance to defend a white man charged with a crime against a black young woman. It is a play about lies. All drama is about lies. When the lie is exposed, the play is over."
The design team for Race includes Santo Loquasto (sets), Brian Macdevitt (lighting) and Tom Broecker (costumes).
Race is produced by on Broadway by Jeffrey Richards, Jerry Frankel, Jam Theatricals, JK Productions, Peggy Hill & Nicholas Quinn Rosenkranz, Scott M. Delman, Terry Allen Kramer/James L. Nederlander, Swinsky Deitch, Bat-Barry Productions, Ronald Frankel, James Fuld Jr., Kathleen K. Johnson, Terry Schnuck, The Weinstein Company, Jay & Cindy Gutterman/Stewart Mercer and Marc Frankel.
