Eleonor Alejandra Marín Mendoza walked out of the General Hospital of Mexico in June 2009 carrying a shopping bag that contained a newborn infant, an exit captured on security footage that ultimately triggered a nationwide criminal investigation. Directed by Oscar-nominated Chilean filmmaker Maite Alberdi, the hybrid documentary film A Child of My Own (originally titled Un hijo propio) examines the true story of how Marín Mendoza faked a pregnancy under intense familial and social pressure, leading to a public scandal and criminal charges.
Origins and Production Details of A Child of My Own
Written by Julián Loyola and Esteban Student and produced by Gato Grande Streaming Network, the 96-minute feature blends dramatic, soap-opera-style reenactments with documentary interview footage featuring the real individuals involved. The narrative centers on Alejandra, a young hospital administrator in Mexico City, and her husband, Arturo Calderón Gamiño. Following three miscarriages, Alejandra faced mounting demands for children from her husband and in-laws. According to the film’s documentation, when Arturo rejected her suggestion of adoption, Alejandra began experiencing bleeding at her hospital post and chose to conceal the loss of her pregnancy rather than report it.
The film’s official Netflix synopsis notes: “Desperate for a baby and burdened by family and societal expectations, a woman fakes a pregnancy and gets tangled in a crime in this shocking documentary.” To maintain the deception, Alejandra gained weight, forged medical records using her access at the hospital, took maternity leave, and hosted a baby shower as her projected due date approached.
Festival Run and Streaming Release Schedule
A Child of My Own debuted internationally at the 76th Berlin International Film Festival, premiering at Berlinale on February 14, 2026. Following its initial German screening, the documentary played at several international film festivals, including Visions du Reel, CPH:DOX, DC/DOX, and the San Francisco International Film Festival. The feature received a theatrical release in Mexico on July 30, 2026, followed by a theatrical run in the United States on August 7, 2026. Netflix subsequently added the film to its global streaming catalog on August 13, 2026. A 2-minute and 46-second official trailer debuted on YouTube on July 15, 2026, previewing the transition from the dramatic reenactments of the fabricated pregnancy to the real-world criminal aftermath.

Arturo served two and a half years before his release. According to the documentary’s tracking of the aftermath, Arturo fathered a child with another woman while Alejandra was incarcerated.
