Handcuffed together, white Caine and black Poitier pursue smuggled diamonds across the veld, and are themselves chased by the Jo'burg fuzz. Mix in some interracial screwing and violence, and Ralph Nelson's got himself a South African Soldier Blue, a sort of tin Gold. Assets there are: Caine is served with some nice deadpan lines by Rod Amateau, and John Coquillon's photography is characteristically cool. But this is an unpleasant and invidious film, like Soldier Blue creaming the surface off profound racial issues to ease the killing along. Its basic attitude is as leering as Nicol Williamson's security cop.
