A dust-covered box hidden in a British manor house for 108 years contains the personal notes of Lord Mersey, the respected British jurist and politician charged with investigating the sinking of the Titanic in 1912.

In 1914, Sir Ernest Shackleton led an expedition to Antarctica but soon after arrival, Shackleton's ship--The Endurance--was destroyed by shifting glaciers, and he was tasked with leading his 27 men across the tundra, on an epic struggle for survival. Shackleton's battle against the odds and his unfailing commitment to bring all his men out alive turned him into a legend. The ship's final resting ground remains one of the greatest polar mysteries. Led by maritime archeologist and shipwreck expert, Mensun Bound, follow a new ground-breaking expedition heading back into the frozen seas to hunt down Shackleton's lost ship.

He was the actor whose most famous role was assassinating a president. But was John Wilkes Booth also an escape artist? Did Booth evade justice and live for decades after killing Abraham Lincoln? For the first time, Booth family members share family lore, and what they believe is evidence of the assassin's escape, passed down through generations.

A former CIA operative's investigation into the Roswell crash arrives at a critical moment when the mysterious journal found among the possessions of Major Jesse Marcel undergoes a crucial test. As a US Army intelligence officer, Marcel was the first government official at the crash site. Investigator Ben Smith is taken to a secret location believed to be the real resting place of the airborne object, as a local archeologist finds evidence that a military cleanup may have taken place. A leading code-breaker continues his attempt to decipher the journal which may be written in a home-brewed code and contain hidden information about what happened at Roswell. And witnesses describe a series of bizarre events surrounding the now legendary crash, while an incredible new technology attempts to read words on a 70 year old photograph that may hold clues to the mystery: Did an extraterrestrial spaceship crash at Roswell?

Investigator Ben Smith travels to Jesse Marcel's hometown on Louisiana's Gulf Coast to speak with family members who reveal information that supports Marcel's story of a government coverup. Smith speaks with Leslie Kean, the investigative journalist who broke The New York Times story about a clandestine U.S. government program to investigate UFOs. Smith also digs deeper into the mystery of the journal as he studies writing samples to determine if the journal might have been written by one of Marcel's fellow officers who later claimed he was ordered to oversee the military's coverup. Back in Marcel's hometown, Smith meets with a man who swears Marcel confided in him about alien bodies-- something Marcel had never mentioned to the press or family. As the results come back from soil, metal and forensic handwriting analysis, Smith shares his findings with the Marcel grandchildren.
