“The Leopards of Zanzibar” (Part 7 of eight) profiles young “free-diving” fishermen on the Tanzanian island off Africa's Swahili Coast. Leopards is the name of their amateur soccer team, which is their passion. “They think about only one thing,” says a woman in their village. But dive they must to make a living, and one fisherman, Issa Simai, can go down 60 feet (for three minutes) in search of octopus. And when he needs more money (for a trip to Dar es Salaam for an important match) he dives for lobster. They're hard to catch but they bring big money at tourist hotels. Joe Morton narrates.
