Bells of San Angelo is a 1947 American Trucolor Western film directed by William Witney and starring Roy Rogers. The first Roy Rogers film shot in Trucolor, this modern day Western mixes half a dozen songs with mystery, international smuggling of silver, violence, a pack of dogs and comedy relief with one character packing a "16-shooter" from which 22 shots can be heard during the musical number "Hot Lead" performed by the Sons of the Pioneers.

Plot

Roy is a "border inspector" ever on the alert for smuggling silver between Mexico and the United States. Roy's Mexican friends have told him that one of their own has important information about a silver mine on the American side of the border, but their contact is shot and killed by the mine guards. Before shooting him, they plant a piece of ore containing a high level of silver on his body.
