[1][2] Shot on location in Spain,[3] it depicts the life and death of Mexican priest Miguel Pro during the Cristero War.

The lead role was played by Humberto Almazán, an actor who left the industry to become a priest and returned to acting for this film.

The movie was the final feature film of director Arthur Lubin.

Diabolique magazine later wrote "this is sometimes called a spaghetti Western, but it isn’t really… It’s more a priest-on-the-run story, where a guitar-playing man of the cloth tries to escape army prosecution during the 1917 Mexican Revolution.

This film’s a hard slog, badly dubbed and veers wildly in tone (one minute the priest is in drag, the next he’s being executed by firing squad).
