Jalisco, 19th century. Diego, a wealthy landowner, secretly marries Amparo, defying her father Juan Manuel, who fiercely opposes the union. Juan Manuel still holds a grudge against Diego, having once been his employer when Diego was just a laborer. Their secret marriage stirs jealousy and resentment, particularly in Octavio, Diego’s servant, and his wife Laura, who harbors unspoken feelings for him. As Diego departs for a military mission in Guadalajara, Juan Manuel, unaware of the marriage, attempts to arrange a match between Amparo and the Spaniard José Luis.
