Sun, surf and sand is the Bali many people know. But the Indonesian holiday island is no tropical paradise for inmates of the notorious Kerobokan prison.

In this rare exclusive, 101 East goes behind the prison walls and barbed wire to meet some of the 1,300 inmates crammed into overcrowded, humid cells.
