Season 1

This pilot launches the saga of the Cannon family as they fight to establish a ranch in the Arizona territory of the 1870s. Marauding Apaches led by Cochise are on the warpath. The Army orders the Cannon family to move on, but Big John Cannon won't budge.

John Cannon's first wife is killed during an Apache raid. Buck, his brother, can't stop Mexican bandits from rustling cattle. Unable to fight on two fronts -- against Mexican marauders and the Indians -- John arranges a defense agreement with his neighbor in Mexico, Don Sebastian Montoya. The Mexican insists that John seal the agreement by marrying Victoria, his daughter, thus solidifying an alliance against the Apache. Moreover, Don Sebastian demands that Victoria's carefree brother, Manolito, come along to guarantee her safety.

Victoria's efforts to overcome husband John Cannon's memory of his first wife are thwarted when Apaches lay siege to their ranch, and she is kidnapped.

Don Sebastian, her father, arrives with armed vaqueros to break the siege and insists his daughter return to the safety of her home in Mexico.

Guest Stars: Warren Stevens as Captain Dabney, Nino Cochise, grandson of Cochise as Cochise.
