A look inside an air raid shelter at an exhibition opened by the Mayor of Westminster.
Various shots of a new air raid shelter exhibition being opened by the Mayor of Westminster. Several people go inside a shelter beside Caxton Hall. Inside the shelter a man turns a handle on some kind of machine (to seal the door?) and a woman arranges gas masks and protective suits on hooks on a wall. Brief shot of the Mayor posing outside with a woman who looks like film star Margaret Lockwood.
Back inside the shelter we see brief shots of people sitting on benches opposite each other and talking and a couple playing draughts.
