The Truthers Review: ★★★☆☆ (3/5)
The Truthers is a slow-burning, psychologically rich Spanish thriller that uses a mysterious family death as the entry point for a genuinely disturbing look at conspiracy thinking, grief, and the terrifying ease with which rational people can lose their grip on reality — anchored by a commanding José Coronado performance that keeps you perpetually uncertain whether his character is a murderer or simply a man swallowed whole by the internet.
It is not a conventional whodunit, and it will frustrate viewers expecting clean resolutions, but for patient audiences willing to sit with ambiguity, it is one of Netflix’s more thoughtful genre offerings of 2026.

There is a particular kind of person that most of us have encountered in recent years. They might be a neighbour, a relative, or a stranger in a comment section. They believe that pharmaceutical companies are hiding cures. That missing children are part of government experiments. That every official explanation is a cover story and every death is suspicious.
The internet did not create these people, but it gave them a community, an algorithm, and a sense of righteous purpose. The Truthers, the new Spanish thriller now on Netflix, is about exactly this kind of person — and about what happens to the family left behind.
The film follows Ruth, played by Stéphanie Magnin, a young woman living in Berlin who receives news that her mother has died back home in a small Galician town. The official story is straightforward — her mother slipped in the shower, hit her head, and died.
There was wine nearby. She had been drinking. Ruth does not believe it. The mother she knew was not a drinker. The blood in the photographs seems wrong. And her father Martín, played by José Coronado — a retired law enforcement officer — is behaving strangely.
He is withdrawn, evasive, and oddly unconcerned with what happened to his wife. He is far more preoccupied with a missing neighbourhood boy named Alejandro, whom he believes was kidnapped and buried by a pharmaceutical company called Certyx.
What follows is a slow, careful tightening of tension as Ruth investigates and the film gradually asks you a question you did not expect: is she any different from her father?
That is the film’s smartest move. The deeper Ruth digs — reviewing security footage, reading autopsy reports, reconnecting with an ex-lover who happens to work for the company at the centre of her father’s conspiracy — the more her investigation starts to mirror the very thinking she is trying to debunk.
Every coincidence becomes a clue. Every ambiguity becomes confirmation. The cognitive bias that drives conspiracy thinking turns out to be remarkably democratic. It does not require a particular level of education or intelligence. It requires only grief, isolation, and a sufficient amount of unresolved uncertainty.
José Coronado is the film’s anchor. His Martín is never entirely sympathetic but never entirely monstrous either. He is volatile and aggressive, capable of genuine cruelty, and simultaneously capable of what looks like real vulnerability.

You cannot read him cleanly, which is exactly what the film needs. Stéphanie Magnin carries Ruth’s emotional journey with believable exhaustion — a daughter whose guilt about abandoning her family fuels an obsession she cannot quite step back from.
The film’s weakness is its procedural mechanics, which are sometimes too thin to carry the psychological weight the story is reaching for. The pace is deliberate — some viewers will call it slow. The resolution is intentionally messy rather than satisfying in the conventional thriller sense.
But the ending is genuinely unsettling in exactly the right way.
The Truthers is now streaming on Netflix.
