In this semi-historical film by Director Rene Cardona, life-long friends somehow find themselves risking not only everything they have worked for, but literally life and limb, when they discreetly become supporters of the Mexican Revolutionary War and none other than folk-hero Pancho Villa himself. Although their missions include helping a gun-runner smuggle American-made firearms across the border and distracting Mexican government troops in the process, they each still find the time to sing ballads, play Mariachi music and fall in love.
