The island of Dublar Char becomes a hub of activity for the five months of the dry season. Fish caught in the Bay of Bengal is dried here before being sent to markets throughout the country. Procurers - dalals - trick street children onto the islands with the promise of a salary. Once there, the children become virtual slaves, their day-long work rewarded with food and shelter only. It is impossible to run away from the island. Abbas travelled to Bangladesh with the international humanitarian organisation, Concern Worldwide.
