Radiolab’s Latif Nasser always believed his name was unique, singular, completely his own. Until one day when he makes a bizarre and shocking discovery. He shares his name with another man: Abdul Latif Nasser, detainee 244 at Guantanamo Bay. The U.S. government paints a terrifying picture of The Other Latif as Al-Qaeda’s top explosives expert, and one of the most important advisors to Osama bin Laden. Nasser’s lawyer claims that he was at the wrong place at the wrong time, and that he was never even in Al-Qaeda. This clash leads Radiolab’s Latif into a years-long investigation, picking apart evidence, attempting to separate fact from fiction, and trying to uncover what this man actually did or didn’t do. Along the way, Radiolab’s Latif reflects on American values and his own religious past, and wonders how his namesake, a fellow nerdy, suburban Muslim kid, may have gone down such a strikingly different path.

We hear the evidence against Abdul Latif Nasser -- at least the evidence that has been leaked or declassified -- and we meet Shelby Sullivan-Bennis, his attorney, who contests more or less every government claim against him. Sullivan-Bennis walks us through the excruciating process that came close to releasing Abdul Latif Nasser in the waning days of the Obama administration, but fell apart at the last minute. He is now technically a free man -- he was cleared for transfer home in 2016 -- yet he remains stuck at Guantanamo Bay, thanks in part to a Presidential Tweet.

Latif turns his focus to Sudan, where his namesake spent time working on a sunflower farm. What could be suspicious about that? Latif scrutinizes the evidence to try to discover whether - as Abdul Latif’s lawyer insists - it was just an innocent clerical job, or - as the government alleges - it was where he decided to become an extremist fighter.

Latif investigates the mystery around Abdul Latif’s classified time in Afghanistan. He traces the government’s story through scrappy training camps, bombed out Buddhas, and McDonald’s apple pies to the very center of the Battle of Tora Bora. Could Abdul Latif have helped the most sought-after and hated terrorist in modern history, Osama bin Laden, escape? The episode ends with a bombshell jailhouse interview with Abdul Latif, the most reliable evidence yet of what was going on in this man’s mind in the months after 9/11.

Latif heads to Guantanamo Bay to try to speak to his namesake. Before he gets there, he attempts to answer a seemingly simple question: why Cuba? Why in the world did the United States pick this sleepy military base in the Caribbean to house “the worst of the worst”? He tours the “legal equivalent of outer space,” and against all odds, manages to see his doppelgänger… maybe.

Despite being cleared for transfer back to his family in Morocco in 2016, Abdul Latif Nasser remains stuck at Guantanamo Bay. Why? Latif talks to some of the civil servants actually responsible for Abdul Latif’s transfer and they tell him a dramatic story of what went on behind the scenes at some of the highest levels of government. It’s a surprisingly riveting story of paperwork, where what’s at stake is not only the fate of one man, but also the soul of America.
