Returned to Earth, only to find their culture and civilisation destroyed, one of the brothers vows revenge and seeks to decimate the planet with intergalactic technology gathered on his travels. To prevent this, his sibling creates a contingency plan that activates the world's protectors - descendants of their own Pacal family. Now, the fate of the planet lies in the hands of three cousins scattered throughout Central and North America who have never even met.
