Gordon Ramsay loves sharks - and this passion leads him on his most personal mission yet: to investigate the controversial dish, shark fin soup. It's estimated that each year 100 million sharks are killed worldwide and Gordon wants to find out if the slaughter is really necessary. Gordon confronts the horrific fate of these beautiful and majestic creatures. He is told their decline is irrevocably damaging the delicate balance of our oceans' food chain. To understand more about the kings of the ocean, Gordon plunges in to swim with the deadly bull shark, in his scariest challenge to date. Sharks are both terrifying and beautiful, but experts believe overfishing is threatening to drive a third of the world's open ocean shark species to extinction. Incredibly, some of the most threatened species remain untouched by international fishing regulations. What Gordon discovers on his journey leads him to campaign against the brutal and destructive shark fishing industry.
