The film presents three interconnected narratives—though their connections are primarily at the beginning and rather superficial afterward—that explore themes of humanity and loyalty within a Mexico City setting that vividly contrasts wealth and poverty. The initial story centers on “Octavio” (Gael García Bernal), who shares a home with his mother, brother, and wife “Susana” (Vanessa Bauche), whom he is clearly attracted to. He struggles financially until his dog demonstrates unexpected fighting ability, leading to a disturbing way for him to earn money. This development provokes "Salgado" (Ricardo Dalmacci) to the point of confrontation, resulting in an accident that links to the second story. That segment introduces “Valeria” (Goya Toledo), who has recently moved into a luxurious apartment with her boyfriend “Daniel” (Álvaro Guerrero) and their dog. Soon after settling in, the dog becomes trapped beneath the floorboards, and they are unable to locate it. As Valeria continues to deal with repercussions from the first segment's events, tensions escalate and threaten their previously idyllic existence. The third story follows "El Chivo" (Emilio Echevarria), a man already established as skilled with a firearm—particularly when offered payment. He portrays himself as an unassuming dog lover struggling financially, but his narrative reveals a darker side fueled by alcohol and milk that culminates in a situation reminiscent of Cain and Abel, providing broader context for the unfolding events. This is not suitable viewing for those easily upset by animal-related content; however, beyond that, it offers a bleak, realistic portrayal of a society divided not only by class—where neither group seems particularly content—but also by gender and age. Bernal delivers a competent performance, although his character felt somewhat underdeveloped. Toledo and Echevarria are both given substantial material to work with as their respective storylines progress. Each episode concludes by demonstrating humanity’s capacity for self-destruction, pettiness, and avarice; yet, there's also space for affection, sorrow, and compassion—though these positive elements feel surprisingly scarce. The film is unsettling at times, but it’s a worthwhile experience if seen on the big screen.
