Gilbert Roland guest stars as the surprise heir to the Montoya ranch in this special two-hour presentation.

The sudden, peaceful passing of Don Sebastian Montoya brings his daughter Victoria, his son Manolito, John Cannon and Buck to the Montoya ranch to attend funeral services and to settle estate matters. All are amazed to learn the will leaves the vast Montoya holding to Don Sebastian's ne'er-do-well brother Don Domingo, a charming, irresponsible rascal currently living in Mexico City. Upon his return to the family home to claim his legacy, Domingo shocks the family by announcing he plans to sell the ranch and travel. A series of unexplained raids on his new-found cattle and property serves to uncover a little-known dimension of Don Domingo
