A group of settlers set off in a caravan to a land that the government has made available to those who want to settle in the Arizona Territory. On a dangerous journey, crossing Apache territory, the settlers risk their lives for a piece of land. But Geronimo, the Apache chief and his men, are not willing to let them through and attack them, decimating the caravan. The settlers will take refuge in a lost fort where they will face the siege of the Apaches.
