This Documentary from 1985 looks at a small independant MC from Yarmouth, England. (Not to be mistaken with the US MC of the same name)
This is a window into the MC world before the Sons of Anarchy makeover. These guys are the dregs. Dirty, broke and living for the moment. No fortune and glory, the only thing holding them together is the brotherhood and the bikes.
While it's got unintentional moments of Spinal Tap hilarity, at the end its a pretty sad story of loss and a dying lifestyle. Trapped between the Law and larger clubs they will soon dissapear, but at least they will try to go down in a blaze of glory.
