Grey House follows a couple whose car crashes on a mountain and subsequently seek shelter in an isolated cabin with somewhat unusual inhabitants. As the blizzard outside continues, the couple becomes less and less sure of what's true and why a sound in the walls keeps getting louder.

Originally developed and produced by A Red Orchid Theatre, the work made its world premiere in Chicago in 2019, directed by Shade Murray; that production won three Jeff Awards, including Best New Work, in 2020. Tom Kirdahy and Robert Ahrens will produce the Broadway premiere.
