The marvelous tale of one fish, the fisherman who first caught her, and how our insatiable appetite for bluefin tuna turned a cottage industry into a massive global dilemma.

In 2004, an enigmatic charter captain named Al Anderson caught and tagged one Atlantic bluefin tuna off New England's coast. Fourteen years later that same fish—dubbed Amelia for her ocean-spanning journeys—was caught again, this time in a Mediterranean fish trap.

Over his fishing career, Al marked more than sixty thousand fish with plastic tags, an obsession that made him nearly as many enemies as it did friends. His quest landed him in the crossfire of an ongoing fight between a booming bluefin tuna industry and desperate conservation efforts, a conflict that is once again heating up as overfishing and climate change threaten the fish's fate.
