Bronco Bob thinks he's found a home in Moonlight Valley, but there's trouble on the Box Double Bar Flying Diamond W Ranch. Cattle rustling leads to an ambush. Kidnapping is mixed with blackmail. And right in the middle of it all is Bronco Bob, who's not only the best bronc rider in the territory but also an amateur magician who uses tricks instead of a gun to take care of trouble when it comes his way. With the help of his cowgal pal, Loretta, Bronco Bob is determined to unravel the mystery without getting anybody hurt. Unfortunately, the bad guy has a different plan--Bob is a problem to be removed. But this proves to be harder than anticipated. Perhaps the hired gunslinger, Wild Willy, put it best when he said, "Tryin' to catch Bronco Bob is like ropin' the wind. You think you got 'em, but when you pull the noose tight, there's nobody there." Action and humor fill this western adventure.
