The first full trailer for HBO’s The Leftovers premiered on the network Sunday night, just before the newest episode of Game of Thrones. The show comes from Lost executive producer Damon Lindelof and is based on Tom Perrotta’s 2011 novel.

In The Leftovers, humanity is rocked by the news that 2 percent of the entire population has suddenly disappeared without reason. Everyone who remains after the Rapture is left to grapple with the mystery of why they did not disappear, sending a small town into chaos. Based on the full trailer, it appears that the story takes place three years after the mysterious event.

Earlier this month, HBO had said that the series would premiere on June 15, but it has since been pushed back two weeks. It was reported that the production hit the pause button after completing the sixth episode.

“We put ourselves on a tight schedule, and we decided to give our production a short hiatus to prep our final episodes,” HBO said in a statement to Deadline earlier this month.

The Leftovers premieres on Sunday, June 29 and runs 10 episodes. The cast includes Justin Theroux and Liv Tyler.
