A subculture exists throughout contemporary suburban Britain that many find hard to comprehend: educated teenagers regularly gather in 'Federations' to inflict terrible wounds on one another.

This 'sport,' originally based on professional wrestling, contains all the ritual and commentary of a WWE bout, but the fighters use a bewildering and quite terrifying array of weapons including staple guns, barbed-wire-encased light tubes and planks covered in thumbtacks. Tournaments are staged in back gardens, car parks and even living rooms; the ensuing carnage is filmed, and highlights posted on the net for a growing army of fans. Using the boys' own words and experiences, Lock Up Your Sons explores the complex psychological and sociological issues surrounding the fighting. Is this extreme violence a means of relieving aggression or a search for a sense of identity?
