I have once seen a movie (or a TV episode, but probably not) with the following plot:
In the beginning, a reporter is making a story on immortality and does interview with a an elderly couple who claim that they can live forever by moving their souls into new bodies. Later, several tragedies happen to him and his family that derail his life and put him into depression. In the end, he finds out that the couple he interviewed are actually capable of stealing bodies as long as soul of the victim is broken and not ready to fight back. So all things that happened to him were part of their plan to use him as a new body for the husband's soul. There is no happy end.
It is all I remember as I watched it 10 or more years ago. I tried several queries on IMDB and Google, but no luck. I am not sure about country where it was made — most probably it is USA, but potentially might be UK/Europe.
Can anyone identify the movie in question?
