A film about the dilemma of South Africans neither white nor black. South Africa's face to the world is white, backed by a sea of blacks. But the real situation is much more complicated, the colour lines, drawn by law through the country's 19-million inhabitants, isolate two million people under the classification' Coloured They are above the blacks and below the whites in the social hierarchy of apartheid. Many of them are the legacy of three centuries of what would now be illicit sexual pleasure - across the colour line. Hugh Burnett has been back to South Africa to make this third film on the Republic's race policies. Tonight's documentary looks at the blurred edge of the colour line where things are not as black and white as they might seem to the outside world.
