On the brink of civil war, the Torrian Alliance continues with its mission to obliterate Star-children across the universe in order to suppress an intergalactic evil. Following the recommendations of his council, King Gregorio Derry reluctantly agrees to send his only son William on a mission to restore honor to his family name. William seeks to complete his assignment, the elimination of a Star-child named Sydney on planet Earth, but when the assassination is delayed he begins to realize an emotional connection with his target. With conspiracy threatening his home planet, and a hidden menace on Earth seeking to secure a vested interest, William finds himself torn between irrevocable duty and sacrificing everything he stands for to defend Sydney. As William and Sydney struggle to overcome their impossible circumstances, they start to wonder if the connection of two Star-Crossed lovers will be enough to save them from certain doom.
