Set in Thatcher-era South London, Babylon follows Blue, a young reggae DJ striving to make his mark on the sound system scene while navigating the everyday racism faced by Black Britons. As tensions mount with employers, neighbours and the police, the film paints a raw portrait of working-class life in Brixton and Deptford during a period of rising racial conflict. Driven by a powerful reggae and dub soundtrack, Babylon has become a landmark of Black British cinema, capturing both the vibrancy of sound system culture and the pressures shaping it.
