What if the free movement of labour were as important an economic principle as the free movement of capital? Imagine what the world would be like if this were true. Imagine the developed nations dependent on a supply of labour from the third world. Companies would own indentured workers, who would be almost slaves, and they would be entirely responsible for them.
So when a fire destroys the warehouse where eighty-seven such workers are housed, and the company which owns them can't find their paperwork... something has to be done with them. Usually, they're sent back to where they came from, but no one knows where these indentured workers call home. It's up to a young civil servant to discover their origin... and when she does, she learns something far more disturbing.
