Apple TV's Silo, a dystopian sci-fi drama, has released a teaser for its third season, taking viewers back to the lush, green beginnings of the silo community, centuries before the current events unfold. Based on the trilogy by novelist Hugh Howey, the series depicts a self-sustaining underground city where the inhabitants live under strict rules due to the toxic wasteland outside. The recorded history of the silo only spans 140 years, and anyone who wishes to leave is granted a one-way trip to clean the external cameras, leading to their demise in the hazardous environment. The story follows key characters like Juliette Nichols (played by Rebecca Ferguson) and Bernard Holland (played by Tim Robbins), who manage the silo's limited technology and resources. Season 2 concluded with a significant cliffhanger, leaving viewers eager to see how Juliette's journey unfolds as she discovers other silos beyond her own.
