Kirk Langstrom's mental state has been deteriorating for years, but in the wake of his violent altercation with the Suicide Squad, he's found himself on the verge of a complete emotional collapse. Luckily (or unluckily) for Kirk, Dr. Harleen Quinzel is offering pro bono-and entirely unsolicited-psychological counseling. As Harley delves deep into his damaged mind, she uncovers tragic events that set the stage for his transformation into Man-Bat in the first place. Will her psychotic brand of psychology help Kirk make peace with his inner demons or leave his mind even more fractured than it was?
