Bob Lazar is one of the few men who knows the truth: He knows extensively about the U.S. government's secret UFO recovery program - and has even worked on decoding and copying the alien technologies himself. Well, that's what he claims anyway - but can we really take it that easy, and dismiss his story as made-up bullshit? What if there really is something to it? If aliens not only exist - but, if they are already among us?
