he Dark Knight Returns is set in a dystopian version of Gotham City in 1986. Bruce Wayne, aged 55,[1] 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. After watching news reports about the Mutants' crimes, Wayne decides to return to his role as a vigilante. On his first night as Batman, he stops multiple assaults – including one on two young girls, Carrie Kelley and her friend Michelle – and targets the Mutants.
While foiling an armed robbery, Batman learns that the criminals are working for Harvey Dent. Previously known as Two-Face, Dent underwent extensive therapy and plastic surgery to reenter society before disappearing. Batman informs nearly-retired 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.
