They are New York's most notorious vigilantes and outlaws. The Man Without Fear. The Immortal Weapon. The Fire. The Bulletproof Man. Loners all.
But when a terrible threat emerges that imperils the entire city, these loners realize that even they simply aren't enough. This quartet already knows that being a vigilante outlaw is hard. But what's even more difficult than being lone avengers of the innocent ... is for a band of loners to work together ... to defend them.
