Dante reunites with MacDuff, his old bounty hunting mentor, looking to join him for one last hunt. Meanwhile, Lucretia - Dante's current partner - is asked to find a man who may hold the key to the Divinity Cluster, human genes believed to have extra-terrestrial origins.
Luc and Dante transport a pair of criminals to a prison on Mercury. When they reach their destination and head to the surface, their loyalties and faith in one another are tested in the blinding heat of Mercury's sun ward side, where the wrong move ends in agonizing death.
