In the latest clip from the upcoming HBO drama The LeftoversDoctor Who veteran Christopher Eccleston preaches to a nearly empty church about how to interpret the rapture-like event that took place three years earlier.

Lost executive producer Damon Lindelof created the series based on Tom Perrotta's 2011 novel of the same name. Here's the official synopsis from HBO:

When 2% of the world’s population abruptly disappears without explanation, the world struggles to come to terms with what happened. Three years later, the HBO drama series, 'The Leftovers' is the story of the people who didn’t make the cut.

Based on the bestselling novel by Tom Perrotta, 'The Leftovers' follows Kevin Garvey (Justin Theroux), a father of two and the chief of police in a small New York suburb, as he tries to maintain some semblance of normalcy when the notion no longer applies. Created by 'Lost' co-creator Damon Lindelof and acclaimed novelist Tom Perrotta, the series is executive produced by Lindelof, Perrotta and 'Friday Night Lights' executive producers Peter Berg and Sarah Aubrey. Lindelof serves as the series showrunner.

Eccleston is joined in the series by Justin Theroux, Amy Brenneman, Liv Tyler, Michael Gaston and Ann Dowd. The Leftovers premieres June 29.
