Sheriff Roy is then entrusted by the townsfolk with a replica of a treasure map said to lead to a fortune in buried gold, and his old partner Jack and a gang of desperados try to get to it first.

[6] Bava biographer Tim Lucas commented that following the release of Once Upon a Time in the West in 1968, Spaghetti Westerns seemed to be in competition with regard to which film could come up with the most flagrantly bizarre characters and situations.

[7] Lead actor Brett Halsey, who had become friendly with Bava during the shooting of their previous film together, the sex comedy Four Times That Night, stated that it became a comedy as "the script wasn't very good; it kind of lent itself to having fun with it", and revealed that Bava had the idea of playing the film for laughs as early as signing on the cast.

[13] Lucas noted that it was not until the success of the humorous Western They Call Me Trinity before the film received an international release and was acquired by Spanish, West German and American distributors in 1972.
