Billed as 'a new and powerfully different kind of motion picture story' upon release, this unusual western concerns the conflict between a priest and a mexican bandito from a night to remember 1958 director roy baker. Father keogh john mills is a catholic priest who arrives in the remote mexican village of quantano to build a congregation, unaware that the town is terrorized by the ruthless criminal anacleto dirk bogarde. An atheist, anacleto has forbidden worship, so when keogh holds services, anacleto retaliates by murdering the locals in alphabetical order. Keogh refuses to back down. Impressed by his valor, anacleto calls his men off and makes the priest an offer he'll spare him if he determines which inspires greater good, 'the singer' the priest or 'the song' religion. Keogh doesn't answer. Meanwhile, one of the clergyman's followers, the young girl locha mylene demongeot, flees when her family, realizing that she's in love with keogh, arranges a marriage with someone more suitable. Anacleto finds the girl and offers keogh another deal. He'll let the girl live if the priest will admit his failure before his congregation.
