Rick, Helga and Lute are commissioned to find the truth about a claim made that Russia’s sale of Alaska to the U.S. was not legally completed in 1867. Once again, their signature sleuthing methods enable them to quickly find the truth and resolve the matter once and for all. Of course, this leads to more offers: uncover the thieves of rough diamonds from a Canadian mine; and help neutralize a threat by radicals to plant bombs in the U.S. During one of their commissioned adventures, the intrepid trio stumble upon a long-hidden stash of gold in an ancient fortress. After hazardous chases around Alaska, Russia, the Mediterranean, Canada and India in seaplanes, helicopters and even a U.S destroyer, the team heads home somewhat frazzled and intent upon seeking less harrowing and dangerous future adventures.
