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 odyssey: down corridors, up lifts, in and out of rooms. Staff, patients, and equipment are everywhere. Now Henry is not sure he will find Grandma after all. This is a hospital odyssey: seen through the eyes of Henry, who finds friends, humour, lots of information, and at last! Grandma.
