The young handyman, Don, quickly realizes that he is not just there to fix things around the ranch, but also to serve as a buffer between the family and the disgruntled locals who resent their wealth and influence in the community. As he navigates this tense situation, he also becomes increasingly drawn to the family's two daughters, Tania and Ximena, who live a hedonistic and extravagant lifestyle.
As Don spends more time at the ranch, he begins to notice strange occurrences that cannot be easily explained. Mysterious symbols appear on the walls of the property, strange noises are heard at night, and a sense of unease hangs over the entire estate. Don starts to investigate further and uncovers a hidden secret about the family that could change everything.
As tensions rise between the locals and the family, and Don becomes more entangled in the mystery of the ranch, he must choose where his loyalties lie. Will he stand by the family who has given him a job and a sense of belonging, or will he align himself with the locals who are fighting against the family's excess and privilege? The Wall of Mexico explores themes of class, race, power, and the supernatural, all within the backdrop of a vibrant and unique setting.
