But “The Wanderers” is far more playful than profound, an exercise in clever storytelling that involves not one, but two big plot twists - one gradually revealed; the other, seismic - and features that glamorous movie star character. As in her 2017 play “The Last Match,” which was presented at the same theater, Roundabout’s Laura Pels, and which also focused on two couples in challenging relationships (rival tennis players and their spouses), Ziegler comes up with some novel stagecraft that doesn’t completely work, but feels largely satisfying nonetheless. And in “The Wanderers,” she collaborates with the well-cast performers and director Barry Edelstein in creating five absorbing characters.
