They study the night sky, watch chimpanzees in the wild, search the beach for rare fossils, and wander into dark caves. And as they explore, they become discoverers. Young and old, they are women and girls who discover the origins of counting and writing, Stone Age cave art, mysterious matter in the universe, and how a puddle of water can be sanitized when heated by the sun.
