More than 2 million child labourers work on cocoa plantations in Ghana and the Ivory Coast, and tens of thousands of children are victims of trafficking and forced labour in cocoa production. Who are these children and why do they work there?

Fifteen of them tell their story in BITTER Chocolate Stories: Bassirou, Valerie, Augustin, Sarata, Mohamed, Cedric, Ghislain, Issaka, Bèbè, Kassoum, Laeticia, Alexis, Cathérine, Josias and Edyon. Because of these children, we - the chocolate consumers thousands of miles away - can eat the chocolate that we enjoy so much.

We take you to the cocoa plantations and hear their stories and the stories of their parents, the cocoa farmers and the people who are trying to put an end to child labour.
