It is the year 5013. Alien life forms, known as Amerzians, have discovered that there is life on the planet Earth. An Amerzian named Sella forms the Guardian Protectors to defend all life forms from the villains of her species, known as the Amerzian Warriors.
Admarcio is the leader of the Amerzian Warriors. He dislikes all humans, except the elderly, whom he views as the experts of humanity. He plans on removing a part of each human being's brain and replacing it with an alien device that will cause them to act like his species.
Humanity still has its own villains. Johnevin is a reformed terrorist whose mission is revealed to him when he dies and has a face-to-face meeting with God. As he explores heaven, he needs to decide whether he will remain in heaven, or return to earth to complete his mission.
