Batman and Harley Quinn

Poison Ivy and Jason Woodrue (a.k.a. The Floronic Man) embark on an ecological quest to save the planet -- and, unfortunately, eliminate most of humankind along the way. To save humanity, Batman and Nightwing are forced to enlist Harley Quinn to catch Poison Ivy, Harley's BFF and frequent partner-in-crime. But Batman's patience is put to the test by the unpredictable and untrustworthy Harley during the twists and turns the reluctant companions face during their bumpy road trip.
