The New Lion of Sonora (2) (S04E15)

In this special two-hour event, Gilbert Roland makes a memorable appearance as the unexpected heir to the Montoya ranch. After the peaceful death of Don Sebastian Montoya, his daughter Victoria, son Manolito, John Cannon, and Buck gather at the ranch for the funeral and to sort out the estate. They are left stunned when the will reveals that the extensive Montoya property is bequeathed to Don Sebastian's wayward brother, Don Domingo, a charming but irresponsible man living in Mexico City. Upon returning to claim his inheritance, Domingo surprises everyone by announcing his intention to sell the ranch and embark on travels. However, a string of mysterious raids on his newly acquired cattle and land reveals a hidden side of Don Domingo.
