the host for the opening is syeda fatima from the bonded labour liberation front of pakistan. as a teenager, fatima worked at a brick kiln herself, in order to experience the workers' suffering at first hand. >> young girls raped by the owners, raped by their masters, raped by their agents. all workers, children, are suffering a very pathetic life. reporter: fatima's dedication has come at a cost. here she's being beaten by police at a demonstration. there have also been several assassination attempts on her and her family. >> when my brother became permanently didisabled, he was a student. i myself was also, and one of my brothers succeeding in saving himsmself because he can run vey fast. that hasn't stopped her from turning up in brick factories to help enslaved workers flee. she and her organisation have smuggled out almost a hundred thousand to date, and protected them from being caught by their exploiters. their flight is often just the beginning of a long process of liberation. >> they kidnapped and tortured my son and demanded a ransom. i went to the police with fatima
