Maite Alberdi’s 'Un Hijo Propio' Debuts on Netflix

The hybrid documentary reframes a 2009 criminal case to examine how social and family pressure shapes women’s choices about motherhood.

Overview

  • The film was released on Netflix Thursday, August 13, 2026, after a festival run that included a world showing at the Berlinale and screenings in Mexico.
  • Director Maite Alberdi uses a mix of interviews, archival material and staged scenes with actors who worked closely with the real people to reconstruct the events and inner life of the woman at the center of the case.
  • The story is grounded in the 2009 detention and later conviction of Alejandra Marín Mendoza, who was sentenced to 13 years and four months and served time at the Centro Femenil Santa Martha Acatitla.
  • Alberdi, a two-time Oscar nominee, has presented the film as a candidate to represent Mexico in the Academy and Goya selection processes, and the production is listed among roughly 16 titles under consideration.
  • Coverage highlights the human costs on both women involved—the accused and the mother of the stolen baby—and frames the film as prompting renewed public debate about cultural pressure to become a parent and the options available today.
