Netflix’s ‘My Daughter’s Father’: Release Date, Plot, Cast and Everything Else You Need to Know About the Family Secret Thriller Ready to Wreck Your Emotions

A doctor racing to save her daughter’s life is about to unearth a secret two decades in the making, and Netflix wants everyone talking about it. The streamer’s newest Spanish language family drama has been building buzz thanks to its gut punch premise, and now the full picture of who is involved and what happens is finally coming into focus.

‘My Daughter’s Father’ centers on a medical crisis that spirals into a reckoning for two families, and if that setup sounds like prestige soap opera territory, that is very much the point. The series is positioned as one of Netflix’s bigger Spanish language swings this summer, and the details that have surfaced so far suggest it earns the hype.

‘My Daughter’s Father’ Release Date

The series, known in its original Spanish as ‘El otro padre,’ is set to premiere on Netflix on Wednesday, July 22, 2026. That release window places it squarely in the middle of the platform’s summer slate, a period Netflix has increasingly used to launch ambitious international dramas aimed at both Latin American and global audiences.

The show’s official synopsis on Netflix frames the stakes plainly, describing a doctor whose search for a kidney donor for her daughter exposes a secret affair and a DNA test that could shatter two families. That framing alone has been enough to generate curiosity, especially paired with a trailer that has already circulated through entertainment outlets ahead of launch.

Netflix has classified the project as a Mexican production, continuing the platform’s steady investment in telenovela adjacent dramas that blend high stakes medical urgency with long simmering family betrayal.

‘My Daughter’s Father’ Plot Explained

The story follows Maca, a doctor and mother whose daughter Julieta suffers a sudden health collapse during a party, an episode that reveals she urgently needs a kidney transplant. When Maca searches for a compatible donor, her husband turns out not to be a match, and the process instead points toward the teenager’s biological father, the result of a past relationship that had been kept hidden for years.

That revelation does not just complicate a medical emergency, it detonates a secret that has sat buried for two decades. The search for a donor becomes the mechanism that forces Maca’s carefully built family life into the open, and the series is described as following the ethical and moral dilemmas that ripple outward once the truth surfaces.

At the center of that fallout is Ricardo, Maca’s husband, who is portrayed as a devoted family man willing to do almost anything once he learns how serious his daughter’s illness is, even if it means risking prison. That willingness to cross lines for family sets up much of the tension viewers can expect once the donor search collides with the buried affair.

The premise leans into a genre Netflix has mined successfully before, the kind of secret laden domestic thriller where a health crisis becomes the catalyst for uncovering exactly the kind of truth a family spent years trying to keep buried.

‘My Daughter’s Father’ Cast

Leading the ensemble is Silvia Navarro as Maca, the physician and mother whose search for answers drives the entire narrative. Navarro previously starred in projects like ‘Juegos interrumpidos’ and ‘Un mundo para mí,’ giving her plenty of dramatic pedigree heading into this role.

Opposite her is Manolo Cardona as Ricardo, Maca’s husband. Cardona is a familiar face to Netflix’s Spanish language audience thanks to earlier roles in shows like ‘Medusa’ and ‘Dime lo que quieres,’ and his casting here signals the show is aiming for the same kind of soapy, high tension storytelling that made those projects click with viewers.

Azul Guaita plays Julieta, Maca’s daughter and the emotional center of the story, whose sudden medical collapse kicks the plot into motion. Guaita is recognizable from her earlier work on ‘Como agua para chocolate.’ Rounding out the principal cast is Erik Hayser as Emilio Martínez, an actor known for ‘Oscuro deseo,’ ‘Accidente,’ and ‘Ingobernable.’

The supporting cast includes Paola Núñez as Yolanda Martínez, along with Emilio Osorio, Sebastián Dante, Romina Poza, Blanca Guerra, Pamela Moreno, and Georgia Alexi rounding out the ensemble of characters caught in the fallout of Maca’s discovery.

Why ‘My Daughter’s Father’ Is Generating Buzz

Netflix has built a reliable pipeline of Spanish language family dramas that punch well above their marketing budgets, and ‘My Daughter’s Father’ arrives with a cast experienced enough to carry that tradition forward. Pairing a medical emergency with a decades old secret gives the show an obvious hook, one that plays well in trailers and even better in the kind of word of mouth that fuels a Netflix Top 10 run.

The show’s premise also taps into something universally uncomfortable, the idea that the people closest to us might be capable of keeping a life altering secret for years without a single crack showing. That tension between domestic normalcy and hidden truth has powered plenty of Netflix hits before, and this cast looks equipped to deliver it again.

With a release date now locked and a cast list confirmed across principal and supporting roles, all that is left is to see whether Maca’s search for a donor plays out with the same emotional wallop the premise promises.

Once Maca’s secret finally reaches Ricardo and Julieta, whose reaction do you think will hit hardest, the betrayed husband, the blindsided daughter, or the biological father who never expected to be pulled back into their lives?
