Ataque con bombas

A toddler in a striped shirt and overalls stands in a modern kitchen, crying and pointing at a glass door as the text "Alerte à la bombe" appears, then the scene cuts to black and white footage of a large air raid siren on a rooftop, followed by a view of a city street with buildings, then people in period clothing rushing into a sandbagged shelter, and finally a man in a dark suit running toward the shelter entrance as others enter.
