Two years ago, Thaslima Begum and Rosie Swash began investigating what happened to babies given up for adoption in Bangladesh in the 1970s.

A new law allowed families around the world to adopt Bangladeshi children for the first time.

But as Thaslima and Rosie dug deeper, they found a system ripe for exploitation.In this episode, they meet a woman called Bibi Hasenaar – a Dutch adoptee who told them an extraordinary story.

She had always believed she had been unwanted by her mother – until the day she discovered that nothing could have been further from the truth.“I never knew that there was somebody on the other side of the world fighting for me,” she tells Nosheen Iqbal.
