The best assassins are the one's who don't know that they are assassins. Hence the premise of Possessor, where assassins possess their target's mind and make them do horrible things. But what happens when your target realizes that something is up and fights for control of their own mind? What you get is a messed up mind trip of a film. Fan's of David Cronenburg's body horror should excited as well, his son Brandon directed this film, and the apple doesn't fall far from the tree!
