In the 23rd century, the humans and the Sandjarrs are allowed to join an intergalactic multi-racial organisation set up 8,000 years before. The humans are seen as a belligerent, underdeveloped race by the other members of the organisation and had been kept out until now. The Sandjarrs had stayed out of interplanetary politics until a war between themselves and the humans broke out. Now Caleb, a human, and Mezoke, a Sandjarr, are paired up and trained as special agents to keep the intergalactic peace.
