(previews start on July 29; opens on Aug. 17) A comedy of liquor, adultery and philosophy, Theresa Rebeck's new play concerns two couples enjoying a none-too-relaxing weekend upstate. Over the course of a boozy evening and a hung-over morning, they debate what constitutes a good life. Evan Cabnet directs Heidi Armbruster, Brian Avers, Jeff Biehl and Katie Kreisler as the quarreling couples.
