Henry is visiting his grandmother in the hospital. When his nanny has to take a call, he decides to go on alone. He knows Grandma well, after all. But the hospital is bigger than he thought, and his visit becomes an adventure: up and down elevators, in and out of rooms. Now Henry isn't sure he will find Grandma after all. Down every corridor, Henry does find people to talk to: staff, patients, and visitors fill his journey with conversation, humor, information—and a wonderful variety of human nature.
