The Queen's Silver Jubilee beats to the sounds of Funkadelic, Sylvester and the O'Jays in Isaac Julien’s feature debut.

Ngozi Onwurah's sole feature to date is a rough diamond of 1990s British cinema, a harrowing blast of grungy exploitation. It begins with a haunting prologue set in North Carolina in 1652, where an Ibo family calmly drown themselves rather than succumb to the chains of slavery. It then jumps forward to immerse the viewer in a fetid slum of the near-future - the titular Terrordome.
