DNA & polygraph test proof in this documentary about the extraterritorial beings that have visited earth before.

Mary Rodwell is Australia's leading authority on extraterrestrial phenomena, her son Chris Rodwell is a vet, a man of science and self-confessed alien skeptic -- their relationship has reached a critical point and something has to give.

Mary's beliefs led to the breakdown of her marriage and left a teenage Chris with some emotional scars, so the topic comes with baggage. Packing nothing but an open mind, Chris has agreed to enter Mary's world via a road trip traversing Australia in order for her to attempt to convince him that the truth really is "out there" and that aliens exist, or she must never discuss the subject with him again.

Mary plans to leave no stone unturned in her efforts to convince Chris. They will meet a host of colorful characters from alien contactees to skeptical scientists. They will take part in a heated debate with university professors, put key witnesses under pressure with polygraph tests and scour the country for concrete evidence of extraterrestrial life.

Along the way they will argue until they are blue in the face about who is right, and for Mary, this really is her last chance to prove to Chris that she hasn't gone loopy and that there really are other beings in the sky above. This is the search for the truth to save a relationship.
