This stock car driver becomes a rat for the police and goes undercover to stop a gang of bank robbing bikers called The Satan's Angels. The movie starts out wit a cool theme song but then the rest of the music they throw in it is disappointing in comparison. Although there is a pretty cool bassline that provides some groovy background music in places and the band that plays in the bar scene, The Birdwatchers, are pretty decent. The whole movie is kinda disappointing though since this bike gang consist of only four people(there are more bikers on the poster than ever appear in the film) and things go along in a pretty usual way for these types of exploitation flicks with very few surprises. So overall it's a pretty lightweight disposable sort of experience. I did dig that 'Wild Rebels' theme song though!
It has been on Mystery Science Theater 3000 if that's your preferred way of ingesting kitschy cinema.
