The plot of the movie is basically the same as John Wick; suspect they altered just enough to avoid being accused copyright infringement. Fortunately, in this movie the 'John Wick' character is played by someone who can act.
Just like the John Wick movies, Nobody meets expectations as a simple violent shoot 'em up movie. Great to watch at the end of the week when one just wants to see something basic with a lot of action that requires little thought. Trust me, you dont to put much thought into this movie's storyline
