During the Mexican Revolution, Pancho Villa is wounded and left his large treasure in gold back in the city of Colón. He is forced to establish an alliance with General Urbina, leader, and he asks seven of his faithful guerrillas to take back the gold that he has hidden in a farm, near the New Mexico border, and which will allow him to pay for a new army and guns. Meanwhile, the Carrancista troopers and the American army are searching for Pancho Villa's army in disarray, to finish them and their leader. The seven men, the General, and a lonesome hired American (Gringo), start up north; on their way, they cross an old guerrilla and his young companion, Maria, a sexy brunette who decide to join them - and soon Maria becomes the General's lover. The Gringo is sent alone to the farm house to see if it is clear, but he finds there Vera Stevens, a widow whose husband was murdered by Villa's men. The Gringo understands that in the same action, his dear wife was murdered, too... and he changes his loyalty to the blonde widow, who is decided to defend her hose with the sheriff and a handful of her farm hands. They do put up a fight when the General and Villa's seven decide on a full out attack. After much bloodshed, Vera and the Gringo are alone, captured, and tortured to tell where the gold is. They manage to escape their bonds, and counterattack, killing all their enemies, and facing the future with some confidence.
