chunk: After experiencing bankruptcy five years later, the Blackadders sell their plantation and travel west in covered wagons to start a new life in California. A Choctaw Indian named Woboga guides them through the journey, and later turns out to be a spy for the antagonist Cheyenne Indian group led by Yellow Chief, who wants secret revenge against the Blackadder family. Through Woboga, Yellow Chief and his men find the ex-Mississippi planters corralled in an enclosed gorge in the Rocky Mountains by Bijou Creek of the South Platte River. They attack with gunfire, killing Squire Blackadder in the process, and capture the rest of the group as prisoners.
