The film consists of a series of tightly interlinked vignettes, the most sustained of which details the story of a man and a woman who are passionately in love. Their attempts to consummate their passion are constantly thwarted, by their families, by the Church and bourgeois society in general.

Short film to a song of love lost and rediscovered, a woman sees and undergoes surreal transformations. Her lover's face melts off, she dons a dress from the shadow of a bell and becomes a dandelion, ants crawl out of a hand and become Frenchmen riding bicycles. Not to mention the turtles with faces on their backs that collide to form a ballerina, or the bizarre baseball game.

Un Chien Andalou is an European avant-garde surrealist film, a collaboration between director Luis Buñuel and Salvador Dali.
