"When freedom is a luxury, resistance is inevitable."

The Government rule the Hub with an iron fist, their strict laws enforced by Derivates, humans with psionic abilities. When one of these Derivates flees her post, they send KC-847, a powerful telekinetic, to bring her back. But KC-847 soon learns he and his team are unprepared for what they find, and their mission goes awry.

Flit, a plucky teleporter, works for the Underground resistance, the last refuge for Derivates wishing to live free of the Government's control. On a routine security patrol, Flit comes across KC-847 and breaks all the rules to bring him back to the Underground.

However, KC-847's arrival brings with it a string of deadly events that threaten the safety of the Underground. Convinced the incidents are more than unfortunate coincidences, Flit refuses to fall back on a false sense of security and drags KC-847 on an investigation that will change the trajectory of Derivate-kind forever.
