Set after the fall of the Empire and before the emergence of the First Order, we follow the travails of a lone gunfighter in the outer reaches of the galaxy far from the authority of the New Republic.

A mercenary reluctantly leads a motley crew of warriors who soon come to realize they've been captured and deposited on an alien planet by an unknown nemesis. With the exception of a peculiar physician, they are all cold-blooded killers, convicts, death squad members... hunters who have now become the hunted.
