PLOT
A man looks at stacks of canisters of film on shelves. He pulls out a few to show real-life events caught on camera. He pulls out spools of film that include clips of the effects of heavy rain, of early attempts to fly, of an auto race with a spectacular series of crashes, and, last, of the destruction of a suspension bridge newly-built near Tacoma, buffeted and then ruptured by wind. None of these events were staged, and the camera caught them.
