A Guardian investigation traces how shrimp sold in major Western supermarkets connects back to Thai fishing boats that use enslaved and trafficked labor. Reporters follow the supply chain from so-called 'ghost ships,' vessels that stay at sea for months or years while crews are bought, sold, and forced to work without pay, through the processing plants that peel the shrimp destined for pet food and supermarket shelves. Workers describe being beaten, threatened, and in some cases killed by boat captains who treat them as disposable. The film lays out documents and interviews gathered during the investigation, showing how the chain runs from recruitment brokers in Myanmar and Cambodia to Thai fishing fleets to the feed mills and processors that supply international retailers. It does not dramatize the material with reenactments; the footage of the boats, the ports, and the survivors' testimony carries the report. The result is a plain accounting of how a common grocery item can be tied to forced labor and violence thousands of miles from where it's sold.
