Mom is asleep jumps to the movies hand in hand with Onza

Published on June 05, 2026 | Translated from Spanish

Production company Onza, responsible for series like Money Heist or Élite, will adapt Máximo Huerta's novel into a film. The story follows a man who discovers a possible secret brother when his mother, suffering from cognitive decline, embarks on a road trip in a motorhome. A family drama that promises unexpected twists.

A man hugs his mother in a motorhome, while she looks at an old map, amidst blurry landscapes and cinematic lights.

A narrative journey with a road movie structure 🚐

The film adaptation will explore cognitive decline from a visual and auditory perspective. Onza plans to use subjective shots and color changes to reflect the mother's confusion. The motorhome will not just be a vehicle, but an enclosed space that amplifies the tension between the characters. The script will maintain the gradual discovery structure, with flashbacks revealing clues about the past. Music will play a key role in marking moments of lucidity and those of memory loss.

Spoiler: the secret brother is not the neighbor 🕵️

Because of course, when your mother loses her memory and suddenly you have a brother you didn't know you had, the first thing you think is that they've hidden a Venezuelan soap opera from you. But no, here the family mystery is resolved between motorhome stops and arguments about who left the toilet seat up. At least, as long as the trip lasts, your mother won't remember that you owe her money.
