Plot summary
Bennett and Yin are shocked to find Joker has escaped Arkham Asylum and seeking to kidnap everyone who brought him down, intending each of his victims to be encased and paralyzed in large playing-card styled boxes. Batman investigates, but soon discovers Joker involved an accomplice to his schemes, prompting him to confront the real criminal. Joker soon proves to be far more devious, not only escaping for real, but leaving Batman in a race against time to save his intended victims from a tragic fate.
