Out of the mists of our past come The Giants. Who were they? Where and when did they live? the phenomena of giants from the beginnings of civilisation to the present time. Filmed in the U.K., Russia, U.S.A., the Middle East and South America, it features authors and scientists such as: Brad Steiger, Zecheria Sitchin, Eric Von Daniken and archaeologists Vendyl Jones and Dr. Jennifer Westwood. In the film, it shows recently deciphered Sumerian clay tablets that are over 5000 years old. They depict celestial giants who gave a jump-start to human civilisation. One of the tablets shows the earth revolving around the sun, along with the other planets in their correct positions. A fact that was considered heresy 400 years ago.
