Triburcio Pérez, a jíbaro, runs for mayor of Machuchal.

Machuchal as a federal agent. He presents his humorous adventures and exploits in the city of New York as Agent 0. The film is an extremely mild spoof of James Bondish-spy films.

The film, which is an ode to Rafael Hernández's song "Lamento borincano", is a social commentary of the political and social policies of the 40's and 50's which led to the abandonment of what was seen by many as the "pure", "virtuous" life of the finca (farm) for the "corrupting" influence of urban centers like San Juan and New York City.

Machuchal is a rural healer that uses ancient methods and herbs as cures, obtaining the confidence of the community for many years. After an emergency in which a child almost dies, Machuchal is persuaded to attend nursing school.

Jíbaro Machuchal inherits a piece of land in Condado Beach. When he arrives, he finds a hotel has been built on his land.
