A Gaia Ciência (1969)

Night after night, not long before dawn, two young adults, Patricia and Emile, meet on a sound stage to discuss learning, discourse, and the path to revolution. Scenes of Paris's student revolt, the Vietnam War, and other events of the late 1960s, along with posters, photographs, and cartoons, are backdrops to their words. Words themselves are often Patricia and Emile's subject, as are images, sounds, and juxtapositions.
