Sir David Attenborough investigates a unique site in southern England where amateur fossil hunters uncovered giant mammoth bones and evidence of Neanderthals. A team of paleontologists and archaeologists soon discover that the site preserves rare evidence of the extinct beasts and early human inhabitants of Britain dating to over 200,000 years ago. What skills did the early humans have to help them survive during the Ice Age? How did they hunt and protect themselves against formidable creatures such as mammoths? With hands-on experiments with replicas of Neanderthal-era spears and stone tools, the world of prehistoric Britain comes to life.

In 2005, filmmaker Jason DaSilva was diagnosed with primary progressive multiple sclerosis, a rare type of MS with no known cure that inflicts a host of progressively debilitating symptoms. In this moving personal film, DaSilva looks back on the challenges he's faced, delves into the science behind MS, and investigates the potential risk factors that may–or may not–have contributed to his rare diagnosis. Refusing to be labeled a "tragic" case, he continues to advocate for people with disabilities and pursue his career as an artist and filmmaker.
