M/S of firemen directing powerful jet hoses over the River Seine; the Eiffel Tower is seen in the background. Various shots of the hoses, machinery at the base of the pipes and very long extendable ladders. A large box is lowered from the top of one of the ladders; there is a little flag flying from the container (I'm not sure what this signifies).
