This is intelligent film (written but co-directed by Zachary Cotler) may not be for the average film and its definitely would be considered as an art house venture. It as a new challenging portrayal of what "privilege" means.
The film centers on a strong performance Jackson Rathbone by as the handyman, "Don". The rest of film works like mystery of the head of the family (brief performance by veteran actor, Esai Morales) works for (including the drug parties of the spoiled offspring).
The other factor is the local townspeople who are in need of the "water well" on the family's property. What really is it? It is "holy", "toxic" or "illegal"? Their stories, and clues from local encounters with nearby people that "Don" ignores since he fascinated with siblings' drug habits and aloof behaviour.
In the midst of this film is the intellectual banter between the wealthy siblings emulates the female characters in the film, "Thoroughbreds" (2017). One could get lost in their rethoric and that's why some reviews are low. Another factor, the wealthy here are not white, but Latinas, spewing random theories about "Post Humanism", class division, and anthropogenic studies.
The character, "Don" (Rathbone) representing the working class, naive in fact maybe, Shakespeare-like "Caliban". They are some weak spots in the storytelling but the cast's performance (Jackson Rathbone, Esai Morales, Marisol Sacramento, etc.) kept some of story's weakness is holder in.
The filming show the lush and rugged exteriors of the US/Mexico's borders landscape. This film is definitely not for the average viewer is seeking by the film's title is basic definition of border themes: immigration but it does as concept plays the ongoing socio-political theme of "us vs. them".
