‘Someone Has to Know’ Review: A Chilling Crime Mystery on Netflix

There are crime stories that hinge on the whodunit—the question of who committed the crime. Others are more interested in the motives, the underlying reasons, the social world surrounding those caught up in it. Someone Has to Know draws from both traditions—the intrigue is there, but the characters matter more than the resolution itself—while also embracing something less tangible: the enigma, the mystery, the unsettling realization that some events simply defy comprehension.

The premise of the series, led by Fernando Guzzoni, is classic, even conventional. A “normal” teenager, seemingly well-liked by everyone, goes out one night with friends and never returns home. What could have happened? His mother (Paulina García) takes it upon herself to investigate his disappearance, mobilizing an entire town in the process. But there are no real clues. The police fail to uncover anything decisive. Everything dissolves into uncertainty.

What’s most baffling—for both the mother and the police investigator played by Alfredo Castro—is how someone can vanish from a nightclub filled with over 300 people without anyone noticing. That’s where the show’s title comes into play: it’s impossible that no one knows—someone has to know something. The series builds itself around that contradiction.

Across its episodes, Someone Has to Know runs into more dead ends than breakthroughs. There’s a couple who own the nightclub and seem suspicious—perhaps too obviously so to be guilty. A local priest hears the confession of someone claiming involvement in the crime but, bound by religious secrecy, cannot reveal what he’s been told. As the mother searches publicly and the investigator works more quietly, the show gradually widens its scope, probing the mystery from multiple angles.

The case is inspired by a real event in Chile: the 1999 disappearance of Jorge Matute Johns. While the series takes liberties with the facts, it preserves the eerie, unresolved atmosphere that still surrounds the case today. At times, Guzzoni leans toward a more conventional investigative narrative, but it soon becomes clear the series is after something else: an examination of how behavior shifts in the face of danger. Everyone goes silent—those who know, and those who don’t. And very little is resolved.

Produced by Fábula and directed by Guzzoni alongside Pepa San Martín, the series paints a portrait of a Chilean society shaped by appearances and silences, where everyone seems to know something they’re unwilling to say for fear of judgment. It touches on performative solidarity, online cruelty, and the darker impulses that surface in cases like this—cases involving the disappearance of a seemingly “perfect” teenager. Perhaps things are more complicated than they appear. Perhaps that performative impulse isn’t limited to outsiders looking in. Even from within, people often behave that way.

Anchored by strong performances from García and Castro—arguably the two most internationally recognized Chilean actors working today, aside from Pedro Pascal—Someone Has to Know delves into ethical, moral, and religious questions, as well as social violence, youth dynamics, and the generational gap that slowly reveals a disquieting truth: we may not know our children as well as we think.
