21-year-old Mexican caregiver Lucila (Anna Diaz) expresses her discomfort with her surroundings as she follows her mother from Mexico to Madrid. The film 'Ashes' presents a broad framework inspired by Brenda Navarro's novel 'Ceniza en la boca.' While addressing the immigrant experience and family ties, the film promises viewers an emotional journey.

The film centers on Lucila's challenging living conditions and her efforts to adapt to her new life in Madrid. The conflicts this young woman from Mexico faces with both her own culture and her new environment evoke deep empathy in the audience. However, the film experiences some issues with pacing in places, which distracts the viewer's attention.

Although Diego Luna's direction strives to enhance the emotional depth of the story, the film overall presents a rather ordinary narrative. While viewers expect Lucila's story to gain more depth, they feel that some scenes are unnecessarily prolonged. 'Ashes' revolves around the theme of immigration, aiming to provide a thought-provoking experience for the audience, but struggles to achieve this goal.
