Scuff is trapped with the ancient Martians on the eve of the calamity that destroyed them. Could he change prehistory or is he doomed to perish in a fiery apocalypse? Zeke struggles to cure his amnesia, aided by a mysterious scientist and aliens. But even if Zeke recovers, what chance has he of returning to Mars for one last stand?
