A Play for You Alone

WNYC: You are waiting for the subway and a woman, a stranger, asks you for the time.
You show her your phone. She tells you she's running late — and then draws you into a conversation that propels you, somehow, into getting on the train with her.
That's how Witness starts. It is one of five 30-minute plays — or as its creators say, "theatrical interventions" — from LONEtheater, running in repertory as part of the undergroundzero festival. And it's unlike anything I've seen before.
