Apple has released the first trailer for the second season of Silo, and it looks like the season will tell us what happens to protagonist Juliette after the jaw-dropping cliffhanger at the end of season one.

The show, based on a series of books by Hugh Howey, is about a community of 10,000 people living in an underground silo that’s intended to protect them from dangerous conditions aboveground. If you’ve been meaning to see the first season and haven’t yet, you probably shouldn’t watch this new trailer; as you might have guessed, it has quite a few mysteries that are fun to experience for yourself.
