It's been six years since their arrival on Carac, in the Alpha Centauri star system. Wielding superior Earth technology and his special abilities, Jason King transforms the once medieval and backward planet into a force to be reckoned with, improving the lives of everyone and winning the favour of King Wilbur, but the ambitious Jason has an agenda of his own and has his sights set on the throne. Meanwhile, a powerful enemy is out to capture Jason, dead or alive.
