Six Brits tackle Indonesia's tuna industry in Bitung on the island of Sulawesi. In the UK, we consume over a billion tins of tuna a year and Bitung's canneries supply to many British supermarkets and sandwich chains.
The Brits live with tuna workers in basic communities, endure 90-degree heat in the canneries and struggle with the harsh realities of life on a traditional wooden tuna boat in the western Pacific. The extreme conditions affect them all in many different ways, as do the hand to mouth existence of the workers they live with.
