When a cocky, jaded tennis star (David Harbour) loses a pivotal match to an inexperienced Romanian player (Steven Boyer), the two men lock into an unlikely battle for dominance on and off the court. Over the course of three encounters on the Grand Slam circuit, AN UPSET by David Auburn (Tony & Pulitzer winner for Proof) peers irreverently, and explosively, behind the locker room door.

After the play, Tony nominees Harbour ("Stranger Things," Hellboy, Who's Afraid of Virginia Woolf?) and Boyer (Hand to God, "Trial & Error") join director Michael Wilson (PoA's Wildwood Park, Broadway's The Trip To Bountiful) and host Claudia Catania for an exclusive talk-back about working with your idols and what it means to be an amateur.

AN UPSET was recorded live at the 52nd Street Project in New York City.
