Overview:When on a cattle drive on Ponderosa land, the Cartwrights and Candy find a dying cavalry officer on the trail. With his last breath, he asks them to go help his commanding officer, Captain Harris. Riding atop a slope, they see Captain Harris and his soldiers fighting off Mexican bandits who are trying to steal the four kegs of gold hidden in the Army ambulance. The Cartwrights and Candy cut right between the soldiers and the Mexican bandits, in a spectacular chase through a little valley and wind up at a high and rocky outcrop, taking cover and assisting the soldiers.
