A small Spanish town, Villar del Río, is alerted to the upcoming visit of American diplomats and its ruling townsmen begin preparations to impress the American visitors, in the hopes of benefiting under the Marshall Plan. Hoping to demonstrate the side of Spanish culture with which the visiting foreign officials would be more familiarized, the Castilian citizens don unfamiliar Andalusian costumes, hire a renowned flamenco performer, and re-decorate their town in Andalusian style, meantime waiting for their uncertain arrival.
Unfortunately the movie Welcome Mr. Marshall! is not yet available on HBO Max.
