What Is Who’s a Good Boy? About?
The premise of Who’s a Good Boy? in 313 words, with nothing given away. The full story follows below.
In a Mexican high school filled with loud celebrations, shifting friendships, and uncomfortable adolescent hierarchies, Chema is a thoughtful but painfully shy senior. He measures himself against classmates who seem effortless with romance and sex, while he remains inexperienced and self-conscious. His genuine passion for music offers another source of identity, but it does little to quiet the feeling that everyone else has moved ahead of him. When attempts to impress girls repeatedly falter, he turns to his uncle Jaimé, whose unconventional advice and borrowed truck make him feel briefly more capable.
When Claudia, a striking new student, arrives and is assigned Chema as her guide, she quickly shows him romantic interest. Yet he is too frightened and uncertain to respond, leaving their connection suspended between attraction, friendship, and unspoken social expectations. Meanwhile, Eli, his longtime friend and prospective musical partner, senses that Chema’s attention is drifting elsewhere. Their fragile triangle introduces the film’s sharper obsessions: jealousy, popularity, loyalty, and the uneasy bargain a lonely teenager may make simply to feel wanted.
The tone is darkly comic but abrasive, grounded in the embarrassment of adolescence rather than polished wish fulfillment. Family encouragement, romantic longing, musical ambition, and school life overlap in ways that can be funny, humiliating, and unsettling. Chema wants to be seen as confident and grown-up, yet his fear of rejection makes every choice more awkward, while the people around him each project different ideas about romance, friendship, and what a boy should become.
Against this charged everyday world, the film introduces a grotesque counterpoint: a creepy park urinator is kidnapped by his victims and made into their pet dog. The macabre image gives the title its wicked edge and throws a shadow of control and degradation across the story. The result is a provocative coming-of-age dark comedy, balancing social satire, adolescent discomfort, and an unnerving undercurrent of desire turned strange.

Spoilers ahead
Chema is a high school senior struggling with the pressure of being the only one among his friends who has not yet lost his virginity. After failing repeatedly to attract girls at school, he receives relationship guidance and the use of a truck from his uncle Jaimé. Things take a turn when the principal assigns him to be a guide for the new student, Claudia. Although she shows immediate romantic interest, Chema is too intimidated to reciprocate, even as he drives her to school and attends exotic dance classes with her.
Meanwhile, his longtime friend Eli hopes to start a band with him for the Las Posadas celebration, but she becomes distressed upon seeing Chema’s closeness with Claudia. Jaimé attempts to help Chema distinguish between a platonic friendship and a romance, specifically warning him about signs like hugging. However, tensions rise when Claudia invites him to a party; despite her attempts to get intimate in her room, Chema’s fear prevents him from acting. His sister later warns him that he risks becoming a “guau”—a “human pet” or servant to a popular girl.
The situation worsens when Claudia invites Chema to be her date for Las Posadas, while secretly inviting another boy named Sebas. After catching them together and narrowly escaping an awkward encounter with Claudia’s mother, Chema is told they are merely best friends. Despite Jaimé renting a limousine and providing condoms for the dance, the night ends in disaster. Claudia tricks Chema into confessing his feelings, only for her and Sebas to mock him in front of Eli, who subsequently abandons him.
After weeks of being rebuffed by Eli, Chema finally finds his voice. Near graduation, he engages in a loud argument with Sebas, declaring that > no one should be a “guau.” This moment of bravery earns him respect from his peers and a reconciliation with Sebas. By graduation, Chema has successfully friendzoned Claudia and won Eli back with expensive gifts. Choosing passion over expectation, he abandons his engineering plans for a career in music. The story concludes on their graduation trip to Cancún, where Chema and Eli are caught having sex in an airplane bathroom.
