The air is toxic. Murder is a business. Nature is for the wealthy. But if you're a good enough assassin, you may be offered an escape. Killing to earn his way out, The Rider is targeted by shadowy corporations, revolutionaries, and rival assassins clawing their way towards the same escape.

An unlikely crew – an astronaut, his intrepid daughter, and a quintet of sympathetic, albeit violent, alien creatures – seek revenge against a space industry baron.
