An oil supply controlled by corrupt hands, murderous assassins who will do anything to keep that power intact - and a group of friends with a wild plan to thwart them all. The Sentinels return in an epic battle against a Big Oil monopoly. As America's dependence on fossil fuel takes hold in the post-World War II climate of economic growth, seven major oil companies join forces to control the industry. They amass obscene profits, squeeze taxpayers, and manipulate supplies around the world. In a plotline eerily reminiscent of today's political climate, the Sentinels fan out across several continents in an intricately plotted mission to bring Big Oil to its knees.
