Frozen for more than 5000 years on a remote mountain pass, Ötzi the Iceman now lies in a refrigerated tomb. He's a survivor from the Stone Age, bearing secrets of how humans lived nearly 1000 years before the pyramids. His mummified corpse pulled from a glacier in the Alps two decades ago has been probed by scientists for the last 20 years. Yet he's still a mystery waiting to be solved. Who was Ötzi? How did he die? Was it in battle? Or was he murdered? After two years of preparation, a risky autopsy against the clock overturns past theories. The Iceman's DNA and last meal surprise the experts. At last they come closer to understanding our ancient past and to solving this case of death in the Neolithic Age.
