Per an official synopsis for Batman: The Long Halloween, Part Two,

Inspired by the iconic mid-1990s DC story from Jeph Loeb and Tim Sale, Batman: The Long Halloween, Part Two continues as the Holiday Killer is still at large and, with Bruce Wayne under the spell of the venomous Poison Ivy, Batman is nowhere to be found. Liberated by an unlikely ally, Bruce quickly uncovers the real culprit: Poison Ivy's employer Carmine Falcone. The Roman, his ranks decimated by Holiday and his business spinning out of control, has been forced to bring on less desirable partners - Gotham City's rogues' gallery.

In the meantime, Harvey Dent is confronting battles on two fronts: attempting to end the mob war while also dealing with a strained marriage. And, after an attack that leaves Harvey hideously disfigured, the District Attorney unleashes the duality of his psyche that he's strived his entire life to suppress. Now, as Two-Face, Dent decides to take the law into his own hands and deliver judgment to those who've wronged him, his family and all of Gotham. Ultimately, the Dark Knight must put together the tragic pieces that converged to create Two-Face, the Holiday Killer, Batman and Gotham City itself.

Batman: The Long Halloween, Part One stars Jensen Ackles as Bruce Wayne/Batman, Naya Rivera as Catwoman/Selina Kyle, Josh Duhamel as Harvey Dent, Billy Burke as James Gordon, Titus Welliver as Carmine Falcone, David Dastmalchian as Calendar Man, Troy Baker as Joker, Amy Landecker as Barbara Gordon, Julie Nathanson as Gilda Dent, Jack Quaid as Alberto, Fred Tatasciore as Solomon Grundy and Alastair Duncan as Alfred, along with Frances Callier, Greg Chun, Gary Leroi Gray and Jim Pirri. The film is scheduled for release on June 22. Batman: The Long Halloween, Part Two does not currently have a release date.
