Detective Rick O'Shea is an ordinary cop in an extraordinary world of superheroes and super-villains, most of whom are out to kill him, and a few who only want to love him. His job is to keep them from killing each other, made more difficult by a serial killer known as the Reaper. When a riot between superpowers breaks out, and half the downtown area is in ruins, Rick must untangle a web of lies and betrayals, team up with his archenemy, and uncover the true mastermind of the violence before he's busted down to meter-maid and the entire city is reduced to shambles.
