Off the coast of Madagascar, the Vezo people have fished the Indian Ocean by pirogue for generations, reading currents and tides passed down through families rather than sonar. This film follows their traditional tuna fishing alongside the industrial fleets now working the same waters, foreign trawlers and longliners that pull in catches on a scale no outrigger canoe can match. Interviews with Vezo fishermen lay out what is disappearing in real time: shrinking catches, depleted stocks, and a way of life tied directly to a fish now managed by international agreements and distant seafood markets. The film sets local knowledge against global demand, showing how a can of tuna on a European supermarket shelf connects back to a contested ocean and the people who depend on it for daily food rather than profit. It is a portrait of a resource fight playing out unevenly, between subsistence fishermen with no seat at the negotiating table and industrial operators backed by quotas, treaties, and capital.
