On a small island off the coast of Myanmar, Andrew and Brian investigate the mystery of the Ramree Island massacre, where a thousand Japanese soldiers were slaughtered by man-eating crocodiles. Today, they return to that same island to find a crocodile named Whitenose, who is stalking the people on the island and is rumored to be the largest crocodile in the world. Was Whitenose there at the slaughter? And will Andrew and Brian be able to capture this beast?

Andrew and Brian venture out to solve the mystery of the La Concepcion, a shipwreck near the Bahamas where over 300 men were eaten by sharks in 1563. To discover the truth of why the sharks attacked, the two men will attempt to recreate the circumstances of the shipwreck, even going so far as to swim with the sharks at night. Could this swarm have been prevented or could this swarm happen again today?
