The compatibility test was meant to find a kidney donor. It found the wrong kind of answer. Roberto Stopello’s ten-episode Netflix drama runs Mexico’s oldest family secret through a slower, quieter register.

Julieta collapses at her graduation party and needs a kidney transplant. Her family does what families do when medicine runs out of other options — everyone shows up for compatibility testing, because offering what you have is still a form of love. A routine panel returns a number that cannot be averaged away. The man who raised her is not the man her blood came from.

My Daughter’s Father — in Spanish, El otro padre, which translates literally as ‘the other father’ — premiered on Netflix in July 2026 as a ten-episode limited drama produced by Mar Abierto Productions. Roberto Stopello created the series and chose its engine deliberately: the telenovela’s oldest gear, the paternity secret, stripped of its operatic register and run at a quieter speed. Analeine Cal y Mayor and Carlos Villegas Rosales share the directorial credits across the ten episodes.

Silvia Navarro holds the center as Maca, the mother who may have carried the secret for two decades or may be learning it in the same hour as everyone else. The series withholds that answer for as long as it can, and the withholding is architecture rather than delay. Manolo Cardona and Erik Hayser stand on opposite sides of the title: one the father present for every birthday and fever, the other the father the DNA now names. Paola Núñez sharpens the second family, the household that did not know it was implicated. Azul Guaita, as Julieta, is the still point the adults keep circling — the patient whose survival everyone agrees on while quietly disagreeing about who she belongs to.

The direction loads the dread into objects rather than confrontations: the good glassware brought out for a family dinner about to become something else, the framed photographs arranged to tell a story the lab has just contradicted. The performers follow the same logic, pulling back where the genre would offer speeches. The moments that do break the surface arrive harder for having been earned.

The series’ most precise move is built into its title. In English, My Daughter’s Father asserts a bond. In Spanish, El otro padre places an intruder at the edge of the family photograph. Same story, opposite chairs at the same table. The gap between those two titles is where the series lives, and the refusal to close it before the final episode is the contract it makes with the viewer.

The transplant plot resolves on medical terms — donors are found or not, the clock runs to something. The paternity question cannot be settled the same way, because it was never a medical question. A compatibility result names a donor. My Daughter’s Father does not answer what it is built on. That refusal, sustained across ten episodes without losing its shape, is the series’ clearest claim.
