Batgirl patrols the streets of Gotham City.
She finds a young couple causing disaster while tripping on a strange
drug called soul. The woman is in a childlike trance, and the man Jeff
is in a berserk rage. Jeff is strong enough to lift a car over his head
and throw it, but Batgirl knocks him out. The girl looks into Batgirl's
eyes and tells her that she has no soul.

Back at Gotham Clock Tower, Batgirl asks Oracle what a soul is. Oracle is unsure of how to explain it. Oracle asks how Batgirl's recent adventure in Tarakstan
was, and guesses correctly that she is still struggling with Batman.
Oracle comforts Batgirl by explaining that when she was Batgirl, Batman
used to make her cry all the time. Despite this, Oracle reminisces about
how much she loved being Batgirl. Barbara shows Cassandra her old
Batgirl suit, and Cassandra decides to borrow it.

Batgirl returns to her cave and attacks Alfred Pennyworth
as an intruder. Alfred reveals that he has been stopping by once a week
to clean and restock her facilities. He asks if she ever wondered who
was doing this, and she replies that she did not. Alfred talks to
Batgirl about Batman, and assures her that Batman is just worried about
her. Batgirl insists that she can take care of herself, and Alfred
agrees.

Cassandra does research on Barbara Gordon's career as Batgirl,
and decides to go out wearing her old costume. Batgirl takes down a
group of muggers, but accidentally slips on her high-heels. The muggers
laugh at her, and she knocks them out with a batarang. Robin
is dealing with a violent riot of Soul users attacking, and Batgirl
helps him. Robin remarks that she looks particularly hot in this
costume, which he never noticed before. Robin gets clocked in the head,
and Batgirl disperses the other rioters on her own. Batgirl finds a vial
of Soul, and Robin explains that it's a new designer drug. It's
supposed to make you feel blissfully happy, but it has the opposite
effect on some people. Robin takes the drugs back to the Batcave
for analysis. He tells Batgirl that she really does look fantastic in
that costume, but she shouldn't let Batman catch her wearing it.

Batgirl returns to the Clock Tower and gives Oracle back her old
costume. The high heels are broken, but Oracle assures her this happens
all the time. Oracle offers to let Batgirl keep the costume, but Batgirl
declines. Oracle tries to explain what a soul is to Batgirl, as Batgirl
is falling asleep on her couch. Oracle puts a blanket over Batgirl and
lets her rest.
