Watchmen depicts an alternate history in which superheroes emerged in the 1940s and 1960s and their presence changed history so that the United States won the Vietnam War and the Watergate scandal was never exposed. In 1985, the country is edging toward World War III with the Soviet Union, freelance costumed vigilantes have been outlawed and most former superheroes are in retirement or working for the government. The story focuses on the protagonists' personal development and moral struggles as an investigation into the murder of a government-sponsored superhero pulls them out of retirement.
