Three men in dark clothing and face coverings stand in a black void, one holding a bandana with a logo, before the scene cuts to two men in hoodies and caps posing together, then to a single man in a hoodie and cap, followed by a man in a white jersey walking down a dimly lit stone corridor, then a silhouette of a man in a foggy environment, and finally a man in a beanie and patterned shirt looking up in a hazy room. The text "Shut up grace!" appears in the lower left corner throughout.
