Commisioner Jim Gordon has been on the case of several disappearances; murders. All that is left when a body is found are skeletal remains, and whatever is doing this to people is still out there, and increasing the frequency of kills. He has had to turn to Batman for help, especially since the GCPD was tipped off to the possible involvement of Kirk Langstrom - the developer of the Man-Bat Serum. Upon his return to Wayne Manor, Bruce finds that his partner, Catwoman, is displeased to have been left behind for this mission.
