Amusement Mile

Batgirl awoke with a massive headache, shaking out the clouds of confusion to find herself in complete darkness. Beginning to move about, Batgirl discovers that she's encountering tight resistance with her wrist and ankles clamped down on a flat surface

Hearing the sound of a machine starting up, Batgirl feels the slab she's shackled to begin to rise and above her, a hatch opens. Light shining though almost blinds her.

Rising out of the darkness, Batgirl is stunned to see that she is on center stage inside of the dilapidated Big Top tent of Amusement Mile Stands are filled with roaring gang members and thugs wielding various weapons. The Ringmaster happens to be Harley Quinn.
