Anchored well off the African coast, a rusted ship hulk dredges the sea bottom for diamonds, day and night, week after week. This verité look at life aboard the ship records the accumulation of days and the mounting tensions among the crew as the routine grinds along, the tedium builds, the tensions explode. The South Africans hate the Namibians, the Namibians hate the Israelis, the Cubans don’t much care (it’s their ship), and the guy with the toothache just wants the hell off. A raw-edged, absorbing study of men at sea, men at work.
