There have been a series of mysterious disappearances within Bongoman's tranquil Eastlands Estate in Nairobi's urban sprawl. The missing persons reappear days later with no recollection of where they have been and with altered personalities. In the course of his investigations, Bongoman bumps into an alien being who is also looking for him to enlist his services to help in fighting another alien race, building a force to annihilate humankind and take over the earth. Bongoman's scepticism about the existence of aliens is tested as he finds himself forming an alliance of convenience with a star-hopper from a race that can move through dimensions and journey across space at will. Bongoman and his alien partner find themselves in a desperate race against time as they take on an aggressive race of aliens with seemingly invincible powers as they seek to undo what has been done and rid the world of this super race of invaders. In the war to save the world, the duo has to deal with aliens who have taken over the 'essence' of human beings and have mingled with the population. Bongoman must single them out and expel the alien within to save the poor souls.
