The ruthless cattle kaiser Paul Balder, known as El Carnicero, is furious: despite the money he has lavishly poured into the hands of the bandido Macho and his desperados to terrorize the owners of neighboring haciendas, Balder just cant drive out Tex and Carson, who have meanwhile joined up with Kit and Tiger Jack! After the pards have set fire to his bunkhouse and his farm, Balder finances the intervention of the Lupi Rossi, a pack of ferocious Yaquis, but before he can deploy them, the rangers succeed in destroying his ranch by getting it razed to the ground by a herd of demented cows!
