I want to find one movie, but I only know a short scene.
So there is a bomber on a bus, and CIA or FBI agent secretly looks over everyone on a bus, but can’t identify the terrorist. After a while, officially dressed man stands up to get off, and forgets his “breakfast” (paper bag) on his seat. Woman, who was sitting next to this man, shouts to him that he forgot his breakfast. At that moment, the agent realises that his breakfast is a bomb, but it is already too late, and the bus explodes.
Whoever knows the title of this movie, please let me know!! Thank you!
