Since 2002, Eric's team has rescued more than 600 fishing children from slavery. He says most of them come from the central region of the country and then taken hundreds of miles north to the Lake Volta region, where they are forced to work. After a treacherous 10-hour drive, Eric, Lisa and Never must board a ferry that will take them to the remote islands where the children are being held.

Eric says because the area where the children live is so far away from their homes, it's hard for their parents to even know where they are. This distance also contributes to the parents' ignorance of the conditions their children are living in. "We're talking about people who don't have a lot of resources, so they can't exactly take a road trip and go visit their kids," Lisa says.
