Plot

Poison Ivy has controlled the park in the heart of Gotham City since the height of the No Man's Land. Now the new Mayor is determined to remove her from it... even if that means destroying the park in the process. Complicating the matter are the children that have been living under her care.

If Batman can't negotiate her surrender, Gotham's police have been ordered to spray the park with a military-grade herbicide.
