A new designer drug called "Fever" floods the streets of Gotham City, inducing many of the city's teens and preteens to fits of homicidal rage. When Batman sees a group of juvenile Fever addicts kill an old security guard in cold blood, he takes a personal interest in stopping the drug's proliferation. Soon after, Batman raids the Fever pushers' headquarters and forces the pushers to give him the name of their supplier: Scarface. Unbeknownst to Batman, Scarface is actually a wooden puppet operated by a shady nightclub owner known only as the Ventriloquist, who is seemingly a harmless milquetoast, but channels his criminal instincts through an alternate personality that "lives" inside Scarface. Unaware that he is now Batman's latest target, Scarface spends the night shooting one incompetent lackey dead, and sending another to Tijuana on a deadly drug run.
