Atrocious serial killings on holidays in Gotham City send The World's Greatest Detective into action - confronting both organized crime and a unified front of classic DC Super-Villains - while attempting to stop the mysterious mur...

It's the dawn of a new age of heroes, and Metropolis has just met its first. But as Daily Planet intern Clark Kent working alongside reporter Lois Lane secretly wields his alien powers of flight, super-strength and x-ray vision in the battle for good, there's even greater trouble on the horizon.

Inspired by the iconic mid-1990s DC story from Jeph Loeb and Tim Sale, Batman: The Long Halloween, Part One begins as a brutal murder on Halloween prompts Gotham's young vigilante, the Batman, to form a pact with the city's only two uncorrupt lawmen (Police Captain James Gordan and District Attorney Harvey Dent) in order to take down The Roman, head of the notorious and powerful Falcone Crime Family. But when more deaths occur on Thanksgiving and Christmas, it becomes clear that, instead of ordinary gang violence, they're also dealing with a serial killer - the identity of whom, with each conflicting clue, grows harder to discern. Few cases have ever tested the wits of the World's Greatest Detective like the mystery behind the Holiday Killer.

The killer known as Holiday continues to stalk the Falcone crime family while a new class of costumed criminal rises in Gotham City. Batman suspects that a former ally might be the serial killer.
