The Mangrove began as a cafe. But now it is much more. It is a focal point for one of Britain's oldest black communities, with a history central to the growth of black politics and resistance to racism. The people who have made the Mangrove what it is live on the 'front line' in All Saints Road in London's Notting Hill, a tense inner city confrontation zone between police and black people. This film, made by The Mangrove Community Association, examines the impact of policing on the area against the troubled background of race riots in the 1950s, through to the nationwide explosions of anger in the 1980s.
