Boom

A man in a grey t-shirt stands on a paved street lined with trees and a brick building, clapping his hands together repeatedly in a rhythmic motion. The scene cuts to a different man in a tank top and blue cap, who swings a large green leafy branch in a wide arc, then brings it down in a chopping motion. The sequence returns to the first man, who continues clapping. The final frame shows a distant, low-resolution shot of a large explosion on a highway.
