Netflix’s ‘My Daughter’s Father’: Release Date, Plot, Cast and Everything You Need to Know

A doctor racing to save her daughter’s life is about to uncover a secret that has been hidden for two decades, and Netflix is eager for everyone to join the conversation. The streaming platform’s latest Spanish-language family drama has been generating buzz due to its emotionally charged premise, and now the complete picture of the cast and storyline is finally coming into view.

‘My Daughter’s Father’ revolves around a medical crisis that leads to a reckoning for two families. This setup certainly feels like it belongs in the realm of prestige soap operas, which is exactly the intention. Positioned as one of Netflix’s major Spanish-language offerings this summer, the details revealed thus far suggest it lives up to the excitement.

The series, originally titled ‘El otro padre,’ is scheduled to premiere on Netflix on Wednesday, July 22, 2026. This release date places it right in the heart of the platform’s summer lineup, a time Netflix has increasingly utilized to debut ambitious international dramas aimed at both Latin American and global viewers.

The official synopsis from Netflix outlines the stakes clearly, describing a doctor whose quest for a kidney donor for her daughter uncovers a secret affair and a DNA test that could devastate two families. This intriguing setup has already sparked curiosity, especially with a trailer that has circulated through various entertainment outlets ahead of the premiere.

Netflix has categorized this project as a Mexican production, continuing its commitment to telenovela-style dramas that blend urgent medical situations with deep-seated family betrayals.

The narrative follows Maca, a doctor and mother whose daughter Julieta experiences a sudden health crisis during a party, revealing that she urgently requires a kidney transplant. When Maca looks for a suitable donor, her husband turns out to be incompatible, leading the search to point toward the teenager’s biological father, a figure from a past relationship that has been kept secret for years.

This revelation complicates an already critical medical situation and unearths a secret that has been buried for two decades. The quest for a donor becomes the catalyst that forces Maca’s carefully constructed family life into the open, with the series exploring the ethical and moral dilemmas that arise once the truth is revealed.

At the center of this turmoil is Ricardo, Maca’s husband, portrayed as a devoted family man willing to do anything once he learns the severity of his daughter’s illness, even if it means risking imprisonment. His readiness to cross boundaries for his family sets up much of the anticipated tension as the donor search intersects with the hidden affair.

The premise taps into a genre Netflix has successfully explored before: a domestic thriller where a health crisis serves as the trigger for revealing the very truths a family has tried to keep hidden.

Leading the cast is Silvia Navarro as Maca, the physician and mother whose quest for answers propels the entire story. Navarro has previously starred in projects such as ‘Juegos interrumpidos’ and ‘Un mundo para mí,’ showcasing her dramatic talents in this role.

Opposite her is Manolo Cardona as Ricardo, Maca’s husband. Cardona is a familiar face to Netflix’s Spanish-speaking audience, having appeared in shows like ‘Medusa’ and ‘Dime lo que quieres,’ and his casting here indicates the show aims for the same kind of soapy, high-stakes storytelling that resonated with viewers in those projects.

Azul Guaita plays Julieta, Maca’s daughter and the emotional heart of the story, whose sudden medical emergency sets the plot in motion. Guaita is known for her earlier work in ‘Como agua para chocolate.’ The principal cast also includes Erik Hayser as Emilio Martínez, recognized for his roles in ‘Oscuro deseo,’ ‘Accidente,’ and ‘Ingobernable.’

Supporting roles feature Paola Núñez as Yolanda Martínez, along with Emilio Osorio, Sebastián Dante, Romina Poza, Blanca Guerra, Pamela Moreno, and Georgia Alexi, all of whom contribute to the ensemble caught in the aftermath of Maca’s discovery.

Netflix has established a reliable pipeline of Spanish-language family dramas that consistently exceed their marketing budgets, and ‘My Daughter’s Father’ arrives with a cast capable of continuing that legacy. The combination of a medical emergency and a long-buried secret provides an obvious hook, one that resonates well in trailers and even better through the word of mouth that can propel a show into Netflix’s Top 10.

The premise also touches on a universally unsettling concept: the idea that those closest to us might harbor life-altering secrets for years without revealing a hint. This tension between domestic normalcy and hidden truths has fueled many Netflix hits before, and this cast appears ready to deliver that experience once again.

With the release date confirmed and the cast list finalized, the only thing left to see is whether Maca’s search for a donor unfolds with the emotional impact that the premise promises.

Once Maca’s secret finally comes to light for Ricardo and Julieta, who do you think will be most affected—the betrayed husband, the blindsided daughter, or the biological father who never anticipated being drawn back into their lives?
