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 shady manager (Jack Oakie) involves his singer nephew (Wayne Newton) in a Christmas fund-raising drive.

When a neighbor agrees to sell his property, the Cartwrights fear the loss of water rights for their cattle.

A Deputy U.S. Marshal arrives to escort a man to California to testify against a gang; guest Dan Duryea.

The Cartwrights befriend a boy whose father has been sent to jail and whose mother has recently died.
