Our battle-scarred duo decides to bury their differences, down weapons and pick up their tools, in a last-ditch attempt to escape the island. In this nail-biting final episode, it’s all or nothing, as the boys decide flight is their only option. But will our magnificent men take to the skies or will any hopes of finally reaching civilization crash and burn.

With Tory and Richard unable to stand the sight of each other, and with battle lines drawn, blissful island life descends rapidly into all-out war. Even Clarkson gets involved, as the boys build war machines to do battle. But will they destroy more than their friendship?

As Tory channels his despair into making distress signals, Richard does his best to cheer him up by designing an automatic fish-catching device and a range of ‘4th of July’ inspired inventions. But will they see all their hard work go up in smoke?

Even though Richard is more than content in his castaway paradise, Tory remains resolute in his desire to escape the island. Together they launch a daring aquatic bid for freedom, but will their dreams of salvation sink without a trace?

With the intruder captured and having realized rescue is no longer a certainty, the boys decide to pimp their island paradise even further, by adding hydroelectric power to their beachfront treehouse. Tory wants the electricity to signal passing ships but Richard has home comforts on his agenda.

Richard and Tory are shipwrecked somewhere in the Pacific and must use all their smarts to survive, with nothing but the wreckage of their boat and their bare hands. But before constructing the mother of all shelters, of course the first challenge they decide to tackle, is to build a car out of wood!
