"The Dark Knight Returns" is set in a dystopian version of Gotham City in 1986. Bruce Wayne, aged 55, has given up the mantle of Batman after the death of Jason Todd ten years prior. Crime is running rampant throughout the city and a gang calling themselves "The Mutants" has begun terrorizing the people of Gotham. Watching news reports about the Mutants' crimes, Wayne returns to his role as a vigilante. On his first night as Batman he puts a stop to multiple assaults – including one on two young girls, Carrie Kelley and her friend Michelle, and targets the Mutants. While attempting to foil an armed robbery, Batman learns that the criminals are working for Harvey Dent. Dent, previously known as Two-Face, underwent extensive therapy and plastic surgery to reenter society before disappearing. Batman informs a near-retirement Commissioner Gordon that Dent may be planning a larger scheme. Soon after, Dent announces his intention to hold Gotham ransom with a bomb. After Batman defeats Dent and his goons, he discovers that Dent's mind has completely warped into his Two-Face persona.
