In her play Owl Moon, playwright Liz Maestri sent two couples out into a frozen wasteland where they confronted their neuroses and where one pair attempted to dump a body. The result is comic and slightly unnerving, as the characters attempt to figure out just what to do in this situation. Now, Maestri reunites these characters with the actors in Inheritance Canyon, her new play that’s presented as part of the Women’s Voices Theater Festival. This time, Shell and her friends survive a plane crash into a canyon, only to become unwilling participants in a series of government tests that strip them of their autonomy. Things get really interesting when the experiments start to mess with the laws of physics and gravity. Soon enough, the actors will be tumbling across the stage and fighting against the secret government interventions that force them down. The play runs Sept. 18 to Oct. 10 at Capitol Hill Arts Workshop, 545 7th St. SE. $15. (202) 355-9441.
