“He who does not give in to great temptation is not worthy of it.”
The Esponda brothers, Armando and Raúl, arrive in Mexico City in 1949. They are seeking some kind of revenge or family restitution. They are welcomed with unexpected hospitality by their uncle Federico, who enjoys a prosperous economic situation due to a gambling debt that clouds his past. Living with Federico are Josefina and Gladys, the daughters of a deceased business partner. Accepted into the family circle, Armando and Raúl expand the La Merced business, venturing into pharmaceuticals, always skirting the edge of illegality. As if moved by invisible and relentless strings, the brothers marry their uncle’s adopted nieces. Tomás Pellicer, an associate of the Espondas in the opium gum trade, arrives at the Balmori building, where the young couples have moved. The attraction between Gladys and him is unstoppable, and one dawn they run away, leaving Raúl mortally offended. With the fire of revenge burning in their bones once again, the brothers embark on a journey that will lead to a long war against the Pellicer family, not only to get Gladys back, but also to gain control of the streets of Los Angeles and the early drug trade. Demons of Guilt a is a Mexican-style western that tells the story of a family marked by ambition and doomed to tragedy. It is a tale of characters with mythological echoes. It is the story of a Mexico that, although it defines our time, will soon cease to exist.
