Betty, Veronica, and Predator-Archie have been left in the wreckage of their town, all their friends dead. Normally, they'd just go down Memory Lane and get home again where everything's okay, but that's no longer an option. It isn't until they find an undamaged car and drive it down a different road where they can finally return to Riverdale—but their hometown feels different. And it's made even more bizarre when they come face-to-face with a few people they'd never expect: themselves. Only different, newer versions. Little do they know, Predators on Mars are watching them—planning their next attack.
