Someone's freed the lunatics from Le Jardin Noir, France's equivalent to Arkham Asylum, and they'll turn Paris into a living nightmare unless Batman and Robin can get there to stop them.
August's BATMAN AND ROBIN #26 will be written by David Hine and illustrated by Greg Tocchini, and features the psychedelic cover by Chris Burnham shown below.
