Apple has another dark drama coming to its streaming service. Today, the company showed off the first teaser trailer for Silo, a dystopian series based on the novels by Hugh Howey. It starts streaming on Apple TV Plus on May 5th.

The show follows the story of the last 10,000 people left on Earth, who live deep underground in the titular silo to avoid the poisonous surface world. However, the origin of the silo itself remains a mystery and, as the official description explains, “any who try to find out face fatal consequences.” The show stars Rebecca Ferguson, Common, Harriet Walter, Chinaza Uche, Avi Nash, David Oyelowo, Rashida Jones, and Tim Robbins.

Silo joins a growing list of dramas on Apple TV Plus that start with the letter S: it’s now part of a lineup that includes See, Severance, Servant, Suspicion, and Surface. The 10-episode-long first season of Silo will premiere in May with two episodes, followed by weekly releases every Friday.
