The international sex trade criss-crosses the globe using a sinister network made up of criminal masterminds, local handlers, corrupt policemen, wilfully blind politicians, eager consumers, and countless hapless women and children.

In a ground-breaking new work of investigative reporting internationally renowned Mexican journalist and campaigner Lydia Cacho follows the trail of the traffickers and their victims from Mexico to Turkey, Thailand to Iraq, Georgia to the UK. She exposes the trade's hidden links with the tourist industry, internet pornography, drugs and arms smuggling, the selling of body organs, money laundering, and even terrorism.

Lydia Cacho was in conversation with executive director of Article 19, Dr Agnès Callamard.
