King of the Cowboys

It's World War II and saboteurs are menacing Texas. Only singing cowboy Roy Rogers and his wonder horse Trigger can save the day!

The Governor sends Roy to help bring in a gang of saboteurs. Roy joins a traveling show and soon learns the saboteurs communicate during Maurice's mind reading act that uses a hidden receiver. But Maurice is on to Roy. Roy narrowly escapes when Maurice leaves him tied up in a warehouse they are blowing up. But Maurice then kills a man and blames Roy who now finds himself in jail.
