This work, produced by members of the Amigos del Cine de Sabadell association, is considered an exceptional testament to the city's social reality. Blanquer was responsible for the script and direction, while Bardés handled the camera. For weeks, they visited the Coves de Sant Oleguer every Sunday to gain the trust of the protagonists, including a sick child who died shortly after filming and the woman who played his mother.

The short film, presented as a “neo-realist essay” in its credits, reflects the influence of great Italian masters such as Roberto Rosellini, Vittorio De Sica, and Luchino Visconti. The influence of Luis Buñuel, particularly his documentary Las Hurdes (1933), can also be traced, according to Mercè Ibarz.

The plot begins with images of a wheat field and thistles, contrasting with factories in the background, before showing a panoramic view of the caves and their dwellings. The story follows a ten-year-old boy, dressed in rags, to whom his mother gives a piece of bread. The child searches for more food unsuccessfully and is later chased away from a wheat field by a farmer. The film culminates with the child's death, hit by a car, with his mother embracing him while he still holds wheat ears in his hands.

Despite its documentary value, the short film received a poor reception at its premiere at the Centre Excursionista de Catalunya, where it was criticized by other amateur filmmakers. The authors' attempts to add sound were unsuccessful. As Josep Ache wrote, “to silence it, not even the action of the regime's famous censors was needed”.

Joan Blanquer Panadés, born in Castellar del Vallès on May 8, 1912, was a prominent cultural figure in Sabadell. He served as head of human resources at Ferran Casablancas' company and local president of the youth section of Acció Catalana Republicana (ACR). He co-founded the Amics del Cinema association in January 1936 and, after the Civil War, re-established the entity under the name Amigos del Cine. He was a screenwriter for several award-winning amateur films and promoted the Amics de la Filmoteca de Sabadell entity. He also taught Catalan during the Franco regime and was the first president of Òmnium Cultural's Sabadell delegation. He passed away in Sabadell on January 3, 2002.

His colleague, Ramon Bardés Abellà, a cabinetmaker by profession, was born in Esparreguera on October 4, 1910. After his experience with the short film, he dedicated himself to literature, publishing novels such as Sense esperança (1958) and La darrera primavera (1962), and contributed to media outlets like Serra d’Or and the newspaper Avui. He was also a member of the local board of Òmnium Cultural. He passed away in Sabadell on August 19, 1999. The short film is preserved in the Arxiu Històric de Sabadell and is an invaluable document of the reality of immigration and substandard housing of the era.
