A man with spiky hair lies on the floor of a train car, then the scene cuts to a red train moving at high speed, followed by a man with dark hair aiming a pistol down the train aisle, a close-up of his hand gripping the gun, and finally a close-up of his face showing a determined expression. The setting is inside a moving train.
