Very good movie.. but a little confusing. Damian is dying and they transferred his essence into a man they probably killed, Adam. They call him Edward. He must take pills daily to keep Adam’s essence from re-emerging into Adam’s body. Damian/Edward starts remembering his family and searches until he finds them and discovers they are only doing this by killing people, or letting them die. I watched ending several times before I got it. Don’t read more if you know, or you don’t want to know… Damian/Edward goes into isolation and stops taking the pills so Adam’s essence can re-emerge. He leaves a message on the computer to Adam. Tells him everything and that his wife and daughter are waiting on the beach for him. Adam finds them and the family is re-united! I love intelligent, tricky plots in any movie, but sci-fi especially! Loved this movie!
