Cobra Mist explores the relationship between the coastal landscape of Orford Ness and its traces of military history, particularly the extraordinary ruined architecture of experimental radar and the Atomic Weapons Research Establishment. Still under the official secrets act, much of what took place on the Ness will only be revealed over time. Military buildings have been left to the elements to deteriorate, creating a tension between the time it will take for their secrets to come out and for the buildings to disappear. The place has a sinister atmosphere, which the architecture itself begins to reveal or hint at in the film. Cobra Mist records the physical traces of the landscape's often secretive past using the photographic medium of 16mm film and timelapse, constructing an impossible experience of the landscape that evokes its history to the camera.
