Podcast lovers rejoice—Serial is back with a brand new season.

When the podcast Serial premiered, very few people knew who Adnan Syed was. But 100 million downloads and a Peabody award quickly made the alleged murderer a household name. And host Sarah Koenig’s obsessive questioning became an object of adoration and satire.

In Serial’s Season 2 debut, “Dustwun,” the podcast tackles a subject whose face has already been plastered over cable news for years—Army Sgt. Bowe Bergdahl, who disappeared from his post in Afghanistan under mysterious circumstances and was captured by the Taliban. The U.S. government agreed to a prisoner exchange to get him back, trading him for five Guantanamo Bay detainees in May 2014.

Here’s how Koenig describes it on Serial’s site:

This story—it spins out in so many unexpected directions. Because, yes, it’s about Bowe Bergdahl and about one strange decision he made, to leave his post. (And Bergdahl, by the way, is such an interesting and unusual guy, not like anyone I’ve encountered before.) But it’s also about all of the people affected by that decision, and the choices they made. Unlike our story in Season One, this one extends far out into the world. It reaches into swaths of the military, the peace talks to end the war, attempts to rescue other hostages, our Guantanamo policy. What Bergdahl did made me wrestle with things I’d thought I more or less understood, but really didn’t: what it means to be loyal, to be resilient, to be used, to be punished.

Bergdahl himself has not done any press since his return, even as the prisoner exchange created a political furor stateside and he faces an active military court with charges of desertion and endangering troops who searched for him, which carries a potential life sentence.

But now, he speaks. In the premiere Bergdahl explains that he went into the Afghan desert as a whistleblower of sorts, seeking to report issues with his unit at a larger military base. The Serial site’s decription for “Dustwun” reads, “In the middle of the night, Pfc. Bowe Bergdahl grabs a notebook, snacks, water, some cash. Then he quietly slips off a remote U.S. Army outpost in eastern Afghanistan and into the dark, open desert. About 20 minutes later, it occurs to him: he’s in over his head.”

Unlike the first season, Koenig and her crew did not conduct the initial interviews with Bergdahl. Mark Boal, the screenwriter for Zero Dark Thirty, recorded 25 hours of conversation with him for use in a film project, according to The Times. While the Serial team was already working on a second season, they were ready to change gears once presented with the tapes.

Purists might be upset to learn that Serial has modified its theme song for the new season, which Koenig told the Times will probably last eight to 10 episodes.
