The Door Between was based on Anthony the Absolute, a novel by Samuel Merwyn. The story begins in Japan, where American musicologist Anthony Eckert (Monroe Salisbury) is busily collecting records of authentic Japanese folk songs. While thus preoccupied, Eckert makes the acquaintance of a drunkard who has vowed to track down and murder his errant wife.
