A bright blue ribbon tied to a post and words from Walt Whitman’s poetry serve as an ominous start to the teaser for HBO’s new drama series “The Leftovers.”

Based on the bestselling novel by Tom Perrotta, the series follows police chief and father of two Kevin Garvey (played by Justin Theroux) as he tries to maintain normalcy in a world in which two percent of the population has disappeared without explanation.

While the majority of the teaser is rather calm, the intensity amps up in the final seconds, giving viewers the sense that they should expect the unexpected in a world where people vanish without a trace.

The show, exec produced by ‘Lost’ co-creator Damon Lindelof along with Perrotta and ‘Friday Night Lights’ exec producers Peter Berg and Sarah Aubrey, also stars Amy Brenneman, Christopher Eccleston, Liv Tyler, and Ann Dowd. Lindelof, no stranger to shows about mysterious disappearances, also serves as the series showrunner.

“The Leftovers” premieres June 15 at 10 p.m. on HBO.
