What happens when you throw plastic away? Dylan D'Haeze, a 13-year-old filmmaker from the San Juan Islands, decides to find out by following plastic trash to its end source which is the ocean.  As the "downhill to everything", that great blue expanse serves as an unintentional dumping ground and a transportation system as countless pieces of plastic debris wash up on shores around the world. Marine life often ingest plastic debris which ends up affecting human health as those creatures end up on dinner plates.

The film also explores the history of plastics and how they came into wider use due to World War 2 as well as the science of plastics which breaks down the fact that they simply do not break down in nature.

Dylan emphasizes how fellow kids can help make a difference in a world that is increasingly dependent on plastic.
