A film by Anthony de Lotbiniere For the first time television viewers can see behind the scenes of one of the most extraordinary market places in the world - The Risk Market at Lloyd's. In one very large room in the heart of the City of London some 300 underwriters sell £3-milllion worth of insurance cover every working day. There's nothing they won'insure-from a wine taster's palate to a hijack policy -and there's no disaster in the world, be it the failure of the potato crop in Manchuria or an earthquake in Peru, that doesn't affect the remarkable men who operate this unique market. Narration by MICHAEL ADAMS
