Imagine a world where everyone has superpowers. That is, except you. You are the same old turgid, miserable, lonely loser you've always been. But when it comes to superpowers, apparently you can indeed have too much of a good thing. With everyone able to destroy tower blocks with a single punch, any minor fracas escalates into a city-leveling combat, and the world is now in ruins as terrorism and war threaten the very survival of the planet. What's needed is a return to normality, to devolve back from Superhuman to just human - and there's only one man for the job: down-at-heal, divorced New York plumber, Michael Fisher.
