Mackenzie's Raiders

Blood on the Rio (1x15)

:

A flood changes the course of the Rio Grande putting the home of a rancher on the Mexican side of the river. The hot-headed owner ignores Col. Mackenzie's advice to vacate the property until Washington can work out a solution with the Mexican government. In the meantime a gang of outlaws raid the ranch forcing Mackenzie and his trooper to choose between avoiding an international incident or crossing the Rio and attempting a rescue.
