Leon Alastray is an outlaw who has been given sanctuary by Father John, whom he then escorts to the village of San Sebastian. The village is deserted, with its cowardly residents hiding in the hills from Indians, who regularly attack the village and steal all their supplies. When Father John is murdered, the villagers mistakenly think the outlaw is the priest. Alastray at first tells them he is not a priest, but they don't believe it, and an apparent miracle seems to prove they are correct. Eventually, he assists them in regaining their confidence and defending themselves.
Guns for San Sebastian is a 1968 French Western film based on the 1962 novel A Wall for San Sebastian, written by Rev. Fr. William Barnaby "Barby" Faherty, S.J. The film is directed by Frenchman Henri Verneuil, and stars Anthony Quinn, Anjanette Comer and Charles Bronson. The score is by Ennio Morricone, who would then use his work in this film as an inspiration for the main theme in The Mercenary. Filming took place in Sierra de Órganos National Park in the town of Sombrerete, Mexico It was made as a co-production between France, Italy, and Mexico.
It is a rare instance of a French Western actually being shot in Mexico, instead of substituting Spain or some similar European location.
