“Heaven is under our feet to reach for the stars,” writes Henry David Thoreau in Walden. Amy Berryman’s play takes Thoreau’s sentiment into a dystopian near-future, far removed from his 19th-century reflections. With the Earth teetering on collapse, estranged twin sisters grapple with the legacy of their demanding, competitive “NASA hero” father. Stella, played by the Shameless star Emmy Rossum, has abandoned her career as a NASA architect to live off the grid with her fiancé, Bryan. Cassie, played by Succession’s Zoë Winters, is a successful astronaut who’s recently returned from a trip to the moon and is now focused on making Mars a new home for humanity. Both sisters harbor secret envies—Cassie longs for the simplicity of Stella’s life; Stella yearns for Cassie’s achievements. Through their reunion, Berryman explores themes of climate ethics and the balance between happiness, ambition, and responsibility. —Jeanne Malle
