Second Nature (2003)

Everything is not as it seems for a man who recovers from a plane crash in which his family is killed.

His former boss puts him back to work to assassinate a political leader, but when he proves unable to pull the trigger, it is he who becomes the target for assassins. As he avoids capture, the story unfolds about his true past and the reason why he has a tattoo of "chilly willy" inside his lip.
