In Underground Rustlers, the Federal government calls on the Range Busters to foil a plot to steal western gold and enable the cornering of the gold market. Alibi gets a fair amount to do in this one, working undercover as a traveling salesman, while Crash and Dusty operate in the open as government agents trying to safeguard the gold shipments. A good entry in the series.

Mildly recommended. Otto judiciously thinks this movie is OK, but not great.
