My husband and I recently started the show “Silo” on Apple TV+ and it has been interesting so far. The premise is that this society lives in a silo bunker and haven’t been outside for 140 years. It is a punishment to be sent outside to “clean” because you end up dying. The silo is made up of this staircase that they have to use to travel 100 and something floors. There is also a hierarchy between the people down below and those on top. There is a lot mystery and drama going on. We haven’t finished it yet.
