Sort of movie about a prepper.

The original and fully researched out plan to use shipping ISO containers as fully sustaining sub ter retreats is attributed to a British Prepper called John Locke, he did massive amounts of research into ther subject including water proofing, rust proofing, air circulation, security, load stresses for earth piled onto etc. The guy was insanely knowlegable on all aspects of civil defence, I called him my pet archivist I thing he in turn got the concept from early Civil Defence studies.
