This was probably made in a matter of days with a minimal budget and given that, it does better than ok for just under an hour. The Duke, as usual partnered with "Gabby" Hayes is this time embroiled in a dodgy plan to sabotage a new road being built through the Rainbow Valley. His pal - ostensibly, at any rate - "Butch" (Jay Wilsey) is the schemer but will the aptly named "John" be able to thwart this destructive plan? Wayne looks every inch the star here, even in a rather over-sized, but fetching striped prison uniform, and as ever Hayes comes along at just the right moments to ensure a minimum amount of jeopardy with the plot - of which there are a few twists here. It doesn't hang around, there is plenty of action and some quite well choreographed fist fights before a suitably explosive finale.
