The most interesting feature of the Spanish TV series is its structural commitment to the passage of time.

This psychological thriller (often titled Desaparecida in Latin America) features a unique premise where a grieving mother becomes convinced that a stranger's child is actually her own daughter who "died" years ago.

In some Spanish-speaking regions, the digital thriller Missing (starring Storm Reid) is titled Desaparecida . Its standout feature is that the entire movie takes place on computer and phone screens , using "Screenlife" technology to tell the story.

Each episode is named after the number of days since the girl's disappearance (e.g., "Day 1", "Day 4", "Day 18").
