After surviving bloody ambushes by renege Sioux warriors, Lieutenant Colonel Marcus Cavanaugh finds his welcome at Fort Keogh to be hardly a warm one. Major Templeton, the officer who built the fort, is outranked by Cavanaugh and unwilling to play second fiddle to the new commander. With a mutiny and the chain of command endangered, the Sioux begin attacking. Though Cavanaugh orders caution, his subordinate boasts that he could rout the entire Sioux nation with a handful of pony soldiers. The disgruntled major leads his troops straight into a vicious Sioux trap. Now Cavanaugh and the few good men he has left must defeat the savages, and avenge... THE TEMPLETON MASSACRE.
