The young man received a horrible message while watching a movie.

The movie you are looking for is really a missed call, but it is just a ghost call 3. The story is probably about the school leading a classmate to travel, one of the girls didn't go, and then sent a short message to other students by email, asking that classmate to forward the short message to others. He died if he didn't turn around within a limited time, and so did the forwarded one.
