Fragments is a psychological thriller about a man who is deranged. He decides to enter a diner, and while in the diner, he begins shooting customers. This seems to be a random act, and no one knows why the man would decide to take his aggression out on innocent people. There are survivors of the bloody shooting. The survivors all have a different story as they are of various ages from a young girl to the waitress. The young girl is in high school, and she suddenly becomes one of the most popular students because of her telling of what happened.
The waitress who witnessed the act decides to take part in activities with men that are not appropriate while neglecting her baby. There is also a doctor who tries a new experiment that might be able to cure his wife's migraines. These fragments of the lives of people who were affected that day seem to be unrelated, but there could be one connection.
