Secrets of the Stars: Part Two

Plot:

Martin explains that the Ancient Lights, the beings in the shooting star, have selected him as their chosen one to create a new world run by them. Using a radio broadcast he starts to control people all over the world by their star signs to make them compliant. Luke, however, does not have a star sign as he was created, rather than born, can withstand and eventually destroys Martin's control, freeing everybody. Rather than go back to his old life Martin opts to be transformed into a star while Sarah Jane declares the date to be Luke's birthday.
