A 1999 investigative documentary by Irish journalist Donald MacIntyre following the notorious Chelsea Headhunters football hooligan firm, which has ties to the professional Premier league football club Chelsea.
Chelsea F.C has a worldwide following including a group of London-based hooligans which have been involved in racism, riots, theft and violence since the 1960's. This firm was originally called the Chelsea Shed Boys until 1995 when it was changed to the Chelsea Headhunters, most likely to fit in with their activities of hunting down members of rival hooligan firms who support other clubs.
This documentary provides a detailed account of the group's activities as MacIntyre mascaraed as a wannabe member to get in. He even got a Chelsea tattoo for authenticity.
