The Earth has been pillaged and polluted; the sun has not broken through the smog for over a decade. The oceans and rivers have all turned toxic. Man's last hope for survival is to search the ocean depths for alternative fuel, food, and clean water sources. If they fail, mankind will die. The Betty Loo, a search and rescue submarine, captained by Iain Kingston, is hired at for a price no one could refuse. The crew must deal with distrust, sabotage, and spies willing to do whatever it takes to get what they want. What they find on board The Widowmaker the submarine they have been dispatched to help will test each person's will to survive and force enemies to work together. If they don't they will all die, and what rises to the surface will bring hell to Earth.
