On the trawler, the Spirit of Namibia, moored off the coast, diamond mining goes on around the clock. The film follows the life of an international crew working in the service of a faceless mining conglomerate (De-Beers) that owns not only the ship but the surrounding waters as well. The men are drawn into contemplation of their situation. White South Africans spouting racist theories; Cubans who write poetry and speak of love; an Israeli security manager who acts as if he were the enemy; Namibian deck hands who find themselves colonized in their own country. It’s the heart of darkness in which diamonds are forever.
