Killing the one you love most is probably the hardest thing a human being could ever do, and thats what Harry Styles has to do. He works for a bad organization called TEI and is given the position of killing the head of MI6's daughter. Harry agrees and takes on the job, thinking he could go through with it but soon find him self stuck, stuck falling in love with her. Harry then tries to protect her while at the same time not letting her know who he really is and what he's supposed to be doing, that he's supposed to be killing her. Things will happen and people will get hurt, but will it all turn out right.
