Formed millions of years ago by the impact of a comet, the Chesapeake Bay is now one of the North Atlantic's most celebrated Cobia fisheries, and one of its most contested. As the Cobia’s popularity has surged, over-harvesting has taken its toll, leaving behind a population of some of the ocean’s smartest, most elusive game fish. Over the course of one high-stakes day, pro fly angler Blane Chocklett and seasoned waterman Captain Tyler Nonn set out to pursue these powerful giants on the fly. Against a backdrop of shifting tides, the pair must blend skill, patience and instinct to connect with a fish that can vanish in the blink of an eye. More than just a fishing expedition, this is a story of passion, perseverance, and the enduring duel between man and fish.
