Bonanza: Blood On The Land - Volume 1
Ben Cartwright (Lorne Greene) and his three sons, sensible Adam (Pernell Roberts), king-sized Hoss (Dan Blocker), and brash Little Joe (Michael Landon), own the Ponderosa, the largest ranch in Nevada.
When devious sheepherder Jeb Drummond (Everett Sloane) is discovered grazing his flock on the Ponderosa's rich grassland without permission. Ben warns Jeb and his sons Billy (Ray Daley) and Burton (Tom Reese) to clear out. In retaliation, the crooked men kidnap Adam and threaten to kill him unless Ben turns over the entire ranch to them.
