it's not, really. he's sort of the untouchable head of the snake in the movie conflict, but it portrays an organization with deep military, intelligence community, and private security ties engaging in mass murder and assassination to maintain profit.
after being cut loose from some military black op, Markus Mark becomes disillusioned with the US and is a weirdo living in the middle of nowhere for years until he gets pulled into a conspiracy / frame as a lone gunman. the movie is about him on the run and trying to get clear of it all.
it's not a brilliant achievement in film, but it's pretty fun action conspiracy flick about one guy with uncanny ability to survive dog shit scenarios and fire a rifle long distance in a very bleak world. it's got a buddy-cop angle to it, because he pairs up with this junior/nobody FBI guy who is torching his career by questioning the line gunman narrative.
I totally endorse it as a fun pop corn movie. has a few banger lines and some cheesy ones.
