This doesn't explain anything, but it's a drive-around tour of a now-demolished refinery in Lockport IL in 1989 that operated for 80 years. It's also interesting because it's vintage VHS footage with a quirky French soundtrack. To me it scratches the itch of found footage and backrooms (sorta), plus shows just how massive these operations are.
