There are heroes, there are superheroes, and then there's Hancock. With great power comes great responsibility - everyone knows that - everyone, that is, but Hancock. The public has finally had enough -- as grateful as they are to have their local hero, the good citizens of Los Angeles are wondering what they ever did to deserve this guy. Hancock isn't the kind of man who cares what other people think - until the day that he saves the life of PR executive Ray Embrey, and the sardonic superhero begins to realize that he may have a vulnerable side after all. Facing that will be Hancock's greatest challenge yet -- and a task that may prove impossible as Ray's wife, Mary, insists that he's a lost cause.
