Juan (Jorge Mistral) comes back to the village after being wrongly imprisoned for ten years. Alongside his sister Andrea (Carmen Sevilla), they plot revenge against Luis "el Torcido" (Raf Vallone), whom they believe caused their family's suffering. To execute their plan, they join a group of harvesters searching for work in the Castilian fields, where their enemy is also present as their leader.
The movie faced censorship issues, including a ban on its original title "The Reapers" because it coincided with the name of the Catalan anthem. To avoid political controversy, the time frame of the story was shifted from the 1950s to 1935. Eventually, the setting was placed in 1931 to relieve the Republic of any blame for the characters' hardships.
Filming started on June 26, 1957, and wrapped up on September 29 of the same year.
