The story is the second part of a storyline where the adult Franklin Richards travels back in time from the "Days of Future Past" timeline. 

• The Adult Franklin: A powerful, amnesiac man (later revealed as an adult Franklin Richards) appears in New York City. His reality-warping powers are unstable, causing him to unintentionally manifest his childhood dreams and nightmares into the real world.
• The Confrontation: X-Factor (the original five X-Men: Cyclops, Jean Grey, Iceman, Archangel, and Beast) attempts to contain him. The battle is intense because Franklin’s powers are nearly god-like, making him a "living wild card."
• Ahab's Introduction: The issue also features the arrival of Ahab, the terrifying "Hound-master" from the future who has come to retrieve Franklin. Ahab is a cybernetic hunter who turns mutants into "Hounds" to track their own kind.
• The Fantastic Four Connection: Since this is Franklin Richards, members of the Fantastic Four (including the young Franklin’s parents, Reed and Sue) arrive to help, leading to a massive team-up between the two legendary groups.
