Plastic waste in the world's oceans is the subject here, tracked from consumer garbage to open water and back to the food chain. The film opens on the 2011 Japan tsunami and the Fukushima disaster, using the debris and radiation that drifted across the Pacific toward the United States as a case study in how ocean currents move contamination across borders without regard for who caused it. From there it widens into the broader plastic pollution crisis, looking at where discarded packaging ends up, how it breaks down in seawater, and what that means for marine life and the people who eat from it. The film treats this as a shared problem rather than someone else's mess, pressing the case that individual habits and consumption choices feed directly into what shows up in the ocean. It closes without a tidy fix, leaving the scale of the disaster and the question of whether action comes soon enough as the open stakes.
