There will be no central figure for this movie. There will be bunch of superheroes will be featured through out this movie. The plot wasn't myriad to any other superhero's movie that we used to watch before. It is totally different from it own kind. Adapted from a book written by Dave Gibbson, this movie was the main frame of this year 2009.
The story is set in a 1985 where Nixon is a third-term president, America has won the Vietnam War and the course of history has otherwise been changed by two generations of vigilante "costumed adventurers," including one - Dr. Manhattan - who has superpowers and is a key element of the U.S. defense strategy.
But the Cold War is still raging, the current stable of masked heroes has been outlawed by Congress and, as the film opens, the Comedian - a right-wing super-thug who helped assassinate Kennedy and suppressed the Watergate scandal - has been flung to his death from his Manhattan apartment.
Rorschach, a sociopathic do-gooder who wears a mask that looks like a constantly shifting inkblot, investigates and gradually comes to believe that some mysterious conspiracy is afoot to kill off the rest of the retired Watchmen - himself, Nite Owl, Silk Spectre and Ozymandias - and neutralize Dr. Manhattan.
As Rorschach's investigation continues and several of the Watchmen come out of hiding to help him, the attempts on their lives escalate, the Soviet invasion of Afghanistan pushes the world to the brink of nuclear war and all the story strains eventually come together in a shattering - but unexpected - apocalyptic climax.
This is the spine of what is generally regarded to be the greatest of all graphic novels (Time magazine named it "one of the 100 best English-language novels") and a "Moby Dick" of a story that has frustrated three studios and a whole field of filmmakers who have tried to bring it to the screen over the past 20 years.
