The giant tuna is the most powerful fish in the oceans and probably the animal that has influenced the History of Civilization the most. These hot-blooded animals, which can weigh up to one thousand kilograms, travel through the Atlantic Ocean by the hundreds as they carry out the most titanic undertaking in all of marine life. Just a few people know why the influence of this fish has helped determine the history of Humanity: The Red Tuna helped found as well as bring down empires simply because its macerated meat was the only protein available to feed Roman and Greek legions. Nevertheless, the "Great Red" has a weak point, as it is forced to travel into two very dangerous places to reproduce. One of these areas is the Gulf of Mexico and the other the Mediterranean Sea. In the former, the oil spillage is jeopardizing the future of our protagonist, and in the latter, this disaster is just beginning to occur. Besides oil, the tuna has an even bigger enemy; SUSHI, the quintessential Japanese dish. The best tuna in the world can sell for as much as 30.000 Euros for just one specimen in Tokyo. This high price has caused the Tuna War to escalate and has pitted fishermen against ecologists in a long-standing controversy. For the first time in documentary history, we have been able to shoot the reproductive orgy of the tuna in the dark waters of the Mediterranean night. Hundreds of red tunas spreading out eggs and sperm into a huge white cloud in a secret place recently discovered by fishermen. The GREAT RED is about to tell us its story in the first person.
