Synopsis

Chio, an Apache half-breed and his renegades, capture Cannon's supply wagons. Just as food and ammunition for High Chaparral runs out, Chio is captured and brought to the ranch. Meanwhile, Manolito discovers Tina Granger near a burned out stage coach in an apparently unrelated incident. Tina, Chio's daughter, helps him to escape, but leaves her father when he vows to plunder the ranch to gain recognition. Feeling a loyalty to the Cannons who treated her well at the High Chaparral, she leads Buck and Manolito to the stolen supplies and joins them in a dash for the ranch pursued by Chio and his men.
