An indoor swimming pool, likely a maritime training facility in Horten, Norway, is the setting for a simulated emergency exercise. A large, white, boat-like structure, labeled "RS(+) SJØREDNINGSSKOLEN" and "WLL 1000 KG", is performing a controlled capsize or submersion. The structure slowly tilts and sinks into the blue pool water, with several individuals visible inside or near it as it submerges. The pool walls are tiled with wooden paneling above, and feature signs including "NO DIVING" and "5,0m" depth markers. A red buoy or life preserver lies on the wet concrete floor in the foreground, next to the pool. A clock is visible on the back wall.
