Goodnight

A person in a dark environment is struck by a bright flash of light, causing them to fall backward onto a concrete floor. The scene cuts to a close-up of a soldier in a helmet, then to a small object falling on the ground, followed by a shot of a large button on a control panel, before returning to the initial scene of the person being hit by the light and falling. The setting is a dark, industrial-looking space with a stage-like floor and overhead lighting.
