They wanted a romantic weekend by the sea ... They weren't looking for a fight ... But you have to defend yourself ... Right? A ska festival draws thousands of skinheads from across the country to the sleepy seaside town of Cleethorpes. Local residents and day-trippers look on in horror as the town is taken over by shaven-headed masses wearing boots and braces. But much to their surprise, the weekend unfolds peacefully. That is, until a group of drunken bikers think it would be a good laugh to smash up a few scooters, thinking they must belong to mods. Revenge is swift and vicious, but the bikers have friends too. Friends who are more than eager to settle the score.
