Investigative journalist Donal MacIntyre directs this documentary examining how football hooliganism, once a very British disease, has gone global. With football violence having been brought successfully under control in Britain since its heyday in the 1970s and 1980s, there has recently been a worrying rise in violence in Europe, South America, and the United States. In graphic detail this film charts the history of hooliganism both home and abroad, examines the motivation behind those involved, and asks what does the future hold for the hooligan?
