Sophie, a young girl, has an imaginary friend named Zephyr, a retired and highly dramatic dragon. Zephyr constantly imagines mundane household items and situations as epic battles and mythical creatures, such as Sophie’s napping dad as a "Snore-Beast" or a pile of laundry as a "Laundry Monster." Sophie plays along, enjoying his theatrical antics and even helping him "fight" these imaginary foes from their blanket fort.
