Host Meg Wolitzer presents three stories that ask the big, basic questions: Who? What? Where? The characters resonate, the situations are intriguing, and each offers a fully realized world. In “What Animal Are You?,” by Etgar Keret, performed by Willem Dafoe, a celebrity writer and his son play themselves for the media. In Rumaan Alam’s “Nothing Can Come Between Us,” performed by Nathan Hinton, a man goes into sensory overdrive. And a fierce and traditional grandmother tries to find her place in a new world and a new family in Gish Jen’s “Who’s Irish?” performed by Frieda Foh Shen.
