The film follows members of the environmental organization FishAct on a dangerous search for clues in Tunisia. Here, illegal fishing boats snatch catches from local fishing crews and destroy sensitive seagrass meadows as they trawl coastal waters. At local fish markets, illegally caught shrimp receive documentation for export, ultimately ending up on Europe’s dinner plates as a supposedly legal product. According to environmental organizations, illegal fishing still accounts for 26 million tons of produce per year. How are these fishing pirates still being allowed to exploit the world's oceans? The filmmakers look for answers in the Mediterranean, US, EU and Australia, talking to officials, activists and experts.
