The idea behind the movie is an intriguing one.
Death has a plan.
Everybody dies on a schedule, carefully mapped out by death. If you happen to do something that gets you out of that schedule then death will come looking for you to make sure you meet with a well timed ending. In this movie Devon Sawa plays a high school student Alex getting on a plane bound for France as part of a class trip. He has a premonition that the plane is going to crash and makes a huge scene that ends with him, a teacher and several other students being ejected from the plane. Sure enough the plane explodes shortly after takeoff, killing everyone aboard.
