A deaf and mute vagabond finds a large denomination bill in a Mexico City dump, and while he tries to buy something with it, others try to con him into giving it away. The film was selected as the Mexican entry for the Best Foreign Language Film at the 36th Academy Awards, but was not accepted as a nominee.
