Ben Cartwright is the patriarch of an all-male Nevada ranching family. Set during and after the Civil War, "Bonanza" is the story of life on the family's thousand-acre spread, known as the Ponderosa, near Virginia City. Ben has his three sons, each with a different (and deceased) mother. Serious eldest son Adam hopes to follow in his father's footsteps; middle son Hoss is a gentle giant -- physically strong, but sometimes naive; and youngest son Little Joe is the most impetuous and romantic of the offspring.

A potential mayoral candidate attempts to stir up trouble between majority and minority groups in town.

Jeb Drummond is a murderous sheep herder who has Adam taken hostage to try and force Ben to sign over a large section of Ponderosa land to him.

Outlaws attack Little Joe and Hoss on their trip to California to purchase a prize bull.

Attacked by Shoshones while crossing a burial ground, Adam discovers that the Indian woman tending him is white.
