Sinopsis

Find Out what Stephen Biesty's body looks like from the inside by following two tiny explorers through the labyrinth of arteries, veins, bones, and organs that make up a human body. Using special equipment carried in their rucksacks, the intrepid voyagers investigate every nook and cranny of Stephen's body to find out how it works - and what happens if it doesn't! Along the way they meet teams of 'body people' who maintain and service Stephen's body, and who explain what they do & why. From being showered by bile in the duodenum, to begin squashed in a muscle as it contracts, the explores are catapulted from one adventure to another, until they are eventually washed out of Stephen's eye in a torrent of tears caused by his terrible hay fever.
