The world's oceans have become critical. Over fishing and over dumping have raised fears that nations must take steps to protect this vast global resource. Tananger, a mature bull gray whale is part of a round up in Scammons Lagoon in Baja California. Because of an extreme shortage of fossil fuels, David Parks, a "fluker," will ride in a pod on the back of the behemoth.
The whale/man team head north into storming seas. They soon encounter a pirate trawler. A rogue wave, a luxurious pleasure yacht and a container ship carrying stolen toxic chemicals are drawn to a climactic point. The evil Chang Lee leaves his Asian headquarters to take charge of an impending disaster.
A strange congregation of whales pursues the pirates to Prince William Sound and then to College Fjord, the site of some of the largest glaciers in Alaska. David, Tananger and a group of Inuit fisherman confront the pirates inside the massive Harvard Glacier.
The fight in ice caverns is soon brought to a halt by a major seismic disturbance a few miles off the entrance to the Sound and the threat of a tsunami looms large as fears mount of being trapped in the narrow fjord.
