Okay Mexican era Bunuel about a young man traveling by bus to his dying mother's hometown where she has a will on record. If he doesn't recover that will and have his mother put her thumbprint on it, his oldest brother...展开, a very greedy man, will have the legal right to divide the property amongst the family. Most of the film is about the bus ride and the adventures the people on the bus have. There are some very nice scenes and touches, but it doesn't rank as one of Bunuel's strongest. It does, however, contain probably the best surreal sequence of any of his Mexican films. I haven't seen them all, so maybe I should just say a more prominent surreal sequence than his more famous Mexican films, i.e., Los Olvidados, El, or Nazarin (not counting anything he made after he returned to Mexico from Spain after Viridiana, i.e., The Exterminating Angel and Simon of the Desert, both of which are more "pure" surrealism).
