Liberal farmer Pepe has arrived in Santa Fe to visit his aunt, Dona Perfecta. While he's there, Pepe is eager to teach the traditional-minded townspeople a new way of living. Unfortunately for Pepe the people of Santa Fe aren't eager to embrace change, and when the citizens begin to voice resentment Pepe is forced to seek refuge with his sympathetic aunt. Dona Perfecta is just as traditional as any of the other townspeople though, and only suffers Pepe due to the fact that he is family. When Pepe and his cousin Rosario fall deeply in love, the situation quickly comes to a head.
