After spending some time with the Mennonite community in Chihuahua, Reynaldo Olmos goes back to Mexico City and establishes a ministry in the poorest of poor neighborhoods. Is he sincere, or is this a scam?
Ephraim Cabot is an old man of amazing vitality who loves his New England farm with a greedy passion. Hating him, and sharing his greed, are the sons of two wives Cabot has overworked into early graves. Most bitter is Eben, whose mother had owned most of the farm, and who feels who should be sole heir. When the old man brings home a new wife, Anna, she becomes a fierce contender to inherit the farm. Two of the sons leave when Eben gives them the fare in return for their shares of the farm. Meanwhile, Anna tries to cause some sparks by rubbing up against Eben.
Olmos is a corporal of the Civil Guard's Public Order and Prevention service who works in the station of his birthplace, Ezcaray, a small town in La Rioja. Robles is a lieutenant of the Rapid Reaction Group, one of the most prestigious units of the Civil Guard, an urban and modern officer. They see themselves forced to work together if they want to solve the international case which, as luck would have it, has united them in this town in La Rioja. They are polar opposites, but together they make up a great team.
