Dara begins in Ireland at Newgrange, uncovering how the moon shaped time and farming. He meets a farmer and fisherman still guided by lunar cycles, then joins Professor Lewis Dartnell to explore the moon's role in evolution. With Dr. Rohin Francis, Dara examines myths about its effect on behavior, and with Professor Katie Joy, he learns why a new race to the moon is underway - thanks to water locked in lunar rocks.
