Playwrights Horizons launches its Unplugged wing—devoted to minimalist stagings that focus on performance and text—with the world premiere of Jacob Perkins’s ensemble drama about a women’s recovery group that meets weekly for a period that seems to stretch into forever. Les Waters (Dana H.) directs a wow of an ensemble cast led by NYC stage legends Kathleen Chalfant and Elizabeth Marvel and filled out very nicely indeed by April Matthis, Keilly McQuail, Mallory Portnoy ​​and Maria Elena Ramirez.
