With a ruthless kamikaze gang led by a hardened Greek-American biker terrorising the city, the conscientious traffic motorcycle police officer, Ringo--aka Sheriff the Bike-Eater--has got enough on his plate already. Now, to make matters worse, Bilias, Ringo's wild nephew, aspires to become the gang's number one henchman. Will the bike-eating sheriff take this rebellion lying down?
