E-I-E-I-Oh...you weren't kidding.
At some point in history, Old McDonald's farm must have not gone so well, because all he ended up with in the end was a silo. Props to whoever advised him to keep the silo, though, because it sure came in handy [spoiler] when the air got poisoned and the world became uninhabitable outside of said silo [/spoiler].
Anyhoo, Old McDonald's silo works, so all is good. Right?
Nope. [spoiler] The sheriff decides to go outside and die alongside his three-years-dead wife who went crazy. The mayor and the deputy take a looooooong trip downstairs (like, over 140 levels long) to pick out a new sheriff, and everything just goes downhill from there [/spoiler]. Do silos have any special mechanics or anything? Because this one has a bit of a problem.
Lucky for the silo, [spoiler] the new sheriff is a mechanic [/spoiler]. Juliette might not know--or care--a whole lot about politics ([spoiler] such as dealing with the all-powerful IT department [/spoiler]), but she definitely knows her way around machines.
