Inside Secret Government Warehouses

Alien body parts, powerful religious artifacts, UFO wreckage: what exactly is hidden behind heavily guarded doors?

Inspired by Syfy’s hit series, Warehouse 13, NBC News award-winning journalist Lester Holt goes on a global expedition to uncover the truth behind the world’s top secret, mysterious warehouses where super-classified objects are kept, ‘Inside Secret government warehouses.’

Holt capitalizes on exclusive access to restricted sites, traveling from Area 51 in Nevada to deep inside the Vatican secret archives, the centerpiece of Dan Brown’s ‘Angels and Demons,’ interviewing informants, Washington decision-makers, former top military personnel and leading experts.

Among the explosive findings:

* A mandible thought to be not of this world: Potential evidence that alien life was hidden by the United States government at Wright-Patterson Air Force base.

* High level informant who describes huge underground tunnels beneath military installations. Victims (including former U.S. military personnel) of unauthorized government experimentation.

* A former US Air Force pilot ordered to shoot down a UFO in England.

Experts interviewed for the show include John Podesta, Former White House Chief of Staff.
