Batman: Under The Red Hood (2011)

The rain-slicked rooftops of Gotham City now host a new player in the underworld. The Red Hood has emerged, his brutal methods carving a bloody path through the city's criminal infrastructure. Batman recognizes the face beneath the mask—it's Jason Todd, the former Robin who died in a warehouse explosion years ago. Their reunion is anything but warm. The Red Hood's crusade is singular: hunting The Joker, the clown prince of crime responsible for his death. Their conflict forces Batman to confront the limits of his own code against a ghost who refuses to stay buried. The streets of the East End run red with the fallout.
