Actually....i dont believe she "comes back from the dead". She's not a zombie.
I think it takes place before Daredevil.
...but....on IMDB, someone wrote this:
Kirigi and The Order of the Hand send Elektra on a mission to kill the widower Mark Miller -- a man who must pay for an act committed by his grandfather years earlier. Upon being introduced to Miller by his young daughter Abby, however, Elektra aligns herself with him and defends them both from Kirigi's ninja assassins. But is there more to the Millers than meets the eye?
So I don't know the near death experience this person is talking about.
Either way....I'll still see the movie
