Don Chente and Dolores are a married couple that runs a little but very successful restaurant. Because they have been working so hard every day since a lot years, they have some money and properties, so they can send two of their child to study in the United States. The only failure of theirs is, maybe, their son Vicente, a drunk-hard and very tormented man. When their two sons come back to Mexico, they've changed. They feel ashamed of their parents because his business is too vulgar, but they keep asking for money although they don't want to present their parents to their couples.
