As Harley Quinn laments drifting through life, not contributing anything, a knock comes at the door. She answers it, and finds a Mandy Scout selling cookies. After she grabs the box and begins eating the cookies, Poison Ivy is surprised to learn that Harley used to be a Scout herself, although she claims that the cookies were the only good part. Ivy decides that someone should teach those girls some "valuable" life skills, and Harley agrees.

It's not long before Harley has formed a group of "Harley Scouts," all of whom dress like her and follow her twisted moral outlook. Batgirl interrupts the meeting, and when Harley points out that she daren't hit a little girl, she reveals that she brought some "help": the Mandy Scouts. As the girls battle around them, using their badge-begotten skills to considerable (if comical) effect, Harley Quinn fights with Batgirl and successfully subdues her. That being accomplished, she begins to sneak off with the money and cookies - but is caught in the act by both the Harley and Mandy Scouts, who descend upon her...

With Harley Quinn tied to a chair, Batgirl provides Law-And-Order merit badges for everyone in the shape of black-and-yellow Bat-crests.
