Edhi's massive graveyard outside Karachi looks like a war cemetery. In a back street police pick up yet another victim although there is little hope of catching his murderers. Karachi's economy is fuelled by drug dealing, gun running and bribery. The secular MQM party has been blamed for widespread violence, including torture. It's a black joke that when the police hear gunfire, they run in the opposite direction. A millionaire businessman has developed Karachi's only computerised investigation system to try to control crime. But avoiding the battlegrounds is becoming more difficult. We follow one injured woman to hospital where there's little hope of saving her life. Small businesses and shops are too afraid to open and it's difficult to sell anything legal. For many of Karachi's orphans Sattar Edhi is their only hope. Interview with Benazir Bhutto.
