Cyril has heard that although super-dangerous, the waters surrounding the remote archipelago of the Bissagos Islands in Guinea-Bissau are home to a fish known for putting up a brutal fight: the cubera. The problem is that deadly mamba and cobra snakes lie in wait for the right moment to strike and in the coastal seas, man-eating bull sharks hunt for their next prey. But even if he's blessed by the local shaman, between the sharks, snakes, and even stingrays, Cyril has his work cut out for him to find a fish that he's clearly underestimated.
