Women and children are being kept as slaves 400 years after the first traders shipped their human cargo to North America.
Children are handed over to work for wealthy families in Nigeria on false promises of schooling, while women are trafficked across the world to be prostituted or kept in indentured servitude.
Blessing was just six-years-old when her mother arranged for her to work as a servant for a family in the Nigerian city of Abuja, on the promise she would be put through school.
But when Blessing arrived in Abuja, there was no school, instead beatings with an electrical wire, rotten leftovers and endless housework.
