Every year large schools of Bluefintuna migrate to their spawing-grounds in the Mediterranean. Although it has long been established that overfishing has left the tuna stocks close to collapse, these days the whole swarm is captured while spawning. Today nobody knows exactly if the stock is about to collapse. Fact is: the majority of marketed tuna on the Japanese markets is not fertile. At the same time the Japanese cooling-houses are packed with frozen tuna- throughout this Tuna-Fort-Knox the trading companies are keeping prices at a minimum. But the fishermen, too, are facing imminent extinction. They have to continue fishing to pay the credits for their boats. The cold logic of game-theory forces them to overexploit the ressources of their own sons. The film exposes the mechanisms of a value chain in the process of destroying its own basis with a strategy based on shortsighted greed.
