When Scott Wolter gets a call from his friend John DeSalvo, an avid collector of Abraham Lincoln memorabilia, he has no idea that he's about to embark on a quest to learn whether there were a lot more people than just John Wilkes Booth behind the assassination of one of America's most influential presidents. Evidence Wolter uncovers suggests Booth was part of an infamous group of Confederates who formed a secret society called the Knights of the Golden Circle; a group that included influential politicians and rogue raiders like Jesse James. The evidence Scott complies suggests a new twist on the motives behind Lincoln's killing and takes him on a wild ride through the history of the South at the time of the Civil War as seen through the eyes of the Knights of the Golden Circle.

Best-selling author Brad Meltzer and his Decoded team examine claims that John Wilkes Booth actually escaped to freedom after murdering President Abraham Lincoln in 1865. The "official" version of events says federal agents cornered Booth and killed him just days after the assassination. But Brad and the team uncover glaring inconsistencies in that 150-year-old account: Why did the authorities hide Booth's body from public view? Why was Booth autopsy's conducted in complete secrecy in the cramped confines of an ironclad gunboat? Searching for answers to these and other troubling questions, the team finds startling evidence that strongly suggests Booth may indeed have lived into old age without ever facing punishment for his crime.

Dale and Blue examine whether a woman who found a letter hidden behind a picture frame stumbled on a lost piece of Abraham Lincoln correspondence that could be worth up to $1 million dollars.

How will the White House fall in a Life After People? The greatest homes and monuments to the world's leaders are under attack. The White House, Monticello and Versailles are suffering different fates. The bodies of Mao Zedong and Ulysses S. Grant are shrouded in mystery. A toxic ex-Naval base decays in the legacy of the Hiroshima bomb. The President's dog must learn the ways of the wild.

This special offers a rare look inside the grandest building in our nation's history. For the first time, Americans will get a glimpse behind those imposing walls as we reveal what life is really like for those who've lived in the White House.

Piecing together information from secret sources and a two-hundred-year evolution of the White House, investigative journalists and government insiders weigh in on the mystery of an unusual white box and a top-secret construction project dubbed the "Big Dig" that took place outside of the West Wing from 2007-2012. Using little known images, previously classified material and detailed graphics, the search for truth reveals not only what secrets might lay below the White House, but how their existence could affect democracy as we know it.

Moments after the President of the United States is sworn into office he gains access to "The Nuclear Football," a briefcase that contains the most volatile top-secret information in the world--America's nuclear launch codes. The Football is a high profile national secret, but it's only one of many pieces in the classified arsenal at the President's disposal once he assumes the role of Commander in Chief. Journey inside White House history to unveil staggering information about secrets known only to the President, from top-secret intelligence and classified events to covert codes and future technologies. Features exclusive interviews with Washington insiders, including former CIA Director Michael Hayden, former Director of Homeland Security Michael Chertoff, former Vice President Dan Quayle, former White House Press Secretary Dana Perino and Presidential daughter Susan Ford who reveal what it is like to live and work in the White House.

In this episode, we look at the ways that American English has been transformed by American presidents, by the language of sex and romance, by good and bad manners. We'll also explore how easy it is to insult people of different groups without even realizing it. Did you know who invented the phrase Founding Fathers, and what the Founding Fathers originally called themselves? Or how American presidents popularized terms like "three martini lunch," "lunatic fringe" and "keep the ball rolling?" When it comes to insults, did you know that the cheer "hip hip hurray" was originally anti-Semitic, "hooligan" was anti-Irish, and the phrase "in cahoots" was anti-French? When it comes to sex, how did a diet of meat give us the word "mating," why do young men "sow their wild oats," and why is the word "hysterical" an insult to women? And when it comes to manners, we'll explore the strange roots of words like "posh," "snob," "stuck up" and even "hello" and "goodbye.
