Fragments (2008) on Netflix

In an ordinary day, a deranged man has a rampage in a diner and randomly shoots the customers. The survivors of the tragic episode are deeply affected by the shooting and have the most different reactions: the youngster, Anne Hagen, becomes popular at school telling her version of the shooting; her friend Jimmy Jaspersen becomes mute and closes himself to the outer world; the waitress Carla Davenport neglects her baby and has several vulgar relationships with men; Dr. Bruce Laraby loses his self-confidence and tries an experimental treatment to the migraine of his wife; and the compulsive gambler Charlie Archenault believes that he is lucky in the game and gambles all his money but he has a jinx.
