Between the 1970s and the 1990s, under China's strict one-child policy, an unknown number of baby girls were abandoned by their parents who wanted to have a son. Tens of thousands of these unwanted girls were brought to Putien, Fujian, where they were raised by foster families. But their foster parents didn't do this out of the kindness of their hearts. Instead, they had a clear goal: one day the girls were to marry their sons. Decades later, the women have grown up, and they want answers: where did they came from? And why were they traded like a commodity?

Nearly 250,000 South Korean children were adopted to the West as “orphans” in the 60 years following the Korean War. Some to loving homes. Others to tragic ends. Raised in places where they looked like nobody else, many were told to forget their past and be grateful. But the innate desire to understand where you came from has led many Korean adoptees to search for their roots. In the process, they discover lies in their past and families they never knew existed. In this documentary series, correspondent Wei Du travels around the world to meet Korean adoptees and accompany a few on their journey to reclaim who they are. Together, they reveal how an “orphan rescue” mission separated families and erased the roots of hundreds of thousands.
