Peabody Award winning drama series The Leftovers returns for its third and final season April 16 on HBO. In an instant, 140 million people vanished from the face of the earth. The cause of that incredible event remains unknown, and there is no indication that those who are gone will ever be seen or heard from again. Created by Damon Lindelof (Emmy winner for Lost) and acclaimed novelist Tom Perrotta (Election, Academy Award nominee for Little Children), the Peabody Award-winning drama series The Leftovers follows the lives that were forever changed by the event that shook the world on October 14. Filmed on location in Texas and Australia, the show's eight-episode, third and final season begins Sunday, April 16 (9:00-10:00 p.m. ET/PT), exclusively on HBO.

Adapting Tom Perrotta's bestselling novel of the same name, season one explored the dynamics of one family, the Garveys, in the suburbs of New York. Continuing to focus on the ways ordinary people react to inexplicable events, season two uprooted that family and introduced another, the Murphys, as the show ventured into the unexplored territory of Miracle, Texas. In the third season, those families come together as they desperately grasp for a system of belief to better explain what defies explanation. The world is crackling with the energy of something big about to happen, a corresponding bookend to the Sudden Departure that sent them all spinning years earlier, bringing their journey Down Under.

The cast of season three includes Justin Theroux (as Kevin Garvey), Carrie Coon (Nora Durst), Amy Brenneman (Laurie Garvey), Christopher Eccleston (Matt Jamison), Kevin Carroll (John Murphy), Jovan Adepo (Michael Murphy), Scott Glenn (Kevin Garvey Sr.), Lindsay Duncan (Grace), Regina King (Erika Murphy), Chris Zylka (Tom Garvey), Margaret Qualley (Jill Garvey), Janel Moloney (Mary Jamison), Jasmin Savoy-Brown (Evie Murphy) and Liv Tyler (Meg). With the seventh anniversary of the Sudden Departure approaching, Kevin Garvey is at a crossroads. Though no longer tormented by Patti, he still questions if an ordinary life is possible. For Nora, Miracle didn't turn out to be the safe haven she was looking for, and Kevin's strange behavior has made her fear for the stability of their family. But Nora's nothing if not resilient.

Laurie Garvey, who left the Guilty Remnant (G.R.) and became a sworn enemy of her former cult, has rejoined her splintered family in Texas. Steady, watchful and wiser than her years, Laurie's daughter, Jill, seeks stability in her own life. Laurie's son, ex-Holy Wayne follower and former undercover G.R. member Tom, wonders if he can just be a son and brother again. Meanwhile, Matt Jamison's faith in God, and in Miracle, has been rewarded. His wife, Mary, who awakened pregnant from her coma, has resumed life with him. All Matt can do is count his blessings and keep preaching the Word.

Season three also finds the Murphy family affected forever by the faked disappearance of their rebellious teenager, Evie, and by the rogue operation in Miracle, conducted by Meg, the most radical member of the G.R. Hardcore skeptic John Murphy has been shaken to his core by a series of inexplicable events, making him believe there may be miracles in Miracle after all. Erika Murphy, a physician who dabbles in magical thinking, and a mother spurned by the daughter she loves, is smart and tough, but there's only so much she can take. Son Michael, the most religious member of the family, is a faithful Christian who believes he has witnessed an actual resurrection. And while all of them in Miracle are trying to find what is lost, to reconnect, to get better, Kevin Garvey, Sr. (Scott Glenn), the former Mapleton Chief of Police who heard voices in his head, is now at large in Australia.
