A series of disturbing events captivates Gotham City as citizens turn on each other all across town.
When toxicology reports turn up negative it’s left to Batman to determine the source of the problem, bringing him into an encounter with Tweedledum and Tweedledee at an entrance to the mysterious ‘Wonderland’.
With Jim Gordon occupied on a tragic, high-profile case, and madness beginning to take root across the city, can Batman find the source of it all before it’s too late?
