Spain, 1944, a country in turmoil, times are hard. Almost bankrupted by his late father's gambling debts, Ricardo, is forced to scrape a living as a shoe-shine boy, in order to care for his recently widowed sister and to keep them in their family home. Ricardo and his life-long buddies work together as a gang, extracting money from debtors for the town's rich and powerful. When the code of loyalty, that has bonded the four friends for so long, is tested to the limit, it takes them on a terrifying journey into an increasing spiral of violence.
