The political evolution in Chile seeing from three different times: 1937, 1947 and 1970. A film that shows how a revolution cannot be accomplished by electoral means, and how the wealthy class will always attempt to destroy that revolution, with the help of the armed forces, as soon as their privileges are threatened.

The characters are refugees from the war who have arrived in America. Ricardo Moller is a scientist who the war has left sexually mutilated, while Arturo Gonzálvez is a professor who believes that another passenger is insane, unaware that she is his wife accompanied by their children.
