In this movie, the main character and all his relates are suppost to travel with an airplane(don't remember to where). But before the airplane take off, he had to stay, all his family die when the airplane crashes. So after a few days, all people that should be dead reappears like nothing had happened. Then all news and proves about the airplane's crash disappear, everybody starts to treat like the main character was crazy when he tries to convince them about the acident.
When he tries to prove that he is not crazy, everybody starts to chasing and try to capture him... In some point of the movie he discovers that all people from the plane were replace by cyborgs/robots and they are trying to do the same with him.
I watched this movie about 20 or 25 years ago on tv, but don't remember exactly the year. Probably is a north american movie.
