Set around an English teacher at his classroom desk, "What Do They Know?" transforms everyday anxieties into a playful, theatrical journey. The world shifts around him from reality to a homemade fantasy—from grocery stores and rainstorms to birthday parties, movie theaters, and outer space—each scene built with handmade, childlike props. The surreal staging mirrors cycles of grief, absurdity, and quiet hope, blurring performance and reality. What begins as isolation gradually becomes connection, ending where it started, with a smile and a lingering question: what do they really know?
