The opening sequence establishes a deserted, burning town followed by a montage of shots two days earlier showing a normal town. A character drives into town to 1950s music, establishing the initial normal setting. Various scenes then show people going about their daily lives and routines to further convey the sense of normalcy before things become "crazy". The sequence culminates with a man shooting at police during a baseball game, with emphasized sound effects during the gunshot. This is followed by a computerized aerial view, hinting at a conspiracy regarding the people becoming "crazy".
