“Chapter 4: Will the Wise” picks up immediately after the heart pounding cliffhanger as Joyce (Winona Ryder) speeds to the school only to find her son Will (Noah Schnapp) standing in the field unresponsive, with his eyes closed. What she and his friends can’t see is what’s actually happening to Will. The “upside down” has converged with the real world and the events that happen in Will’s visions are directly affecting him in reality.
