Alexandra Trott and her African friend Milly are two teenage angels whose help is enlisted by the Angel Network to take on the frightening forces of the Underworld. Underworld leaders Emambo (a witchdoctor) and Tiboltious have devised a cunning plot of harnessing the youth of the 21st century through the use of a fearful new substance known as emuti. Alex and Milly and their exotic angel weapons are eventually able to defeat these forces and the Angel Network creates an anti-virus to undo some of the damage. The Angel realm can now rest for a little while until they will be called on again to fight the forces of evil in the human world.
