Michael Wood travels throughout the subcontinent, tracing the richness and diversity of its peoples, cultures and landscapes. Through ancient manuscripts and oral tales Wood charts the first human migrations out of Africa. He travels from the tropical backwaters of South India through lost ancient cities in Pakistan to the vibrant landscapes of the Ganges plain. Archaeological discoveries in the Bactria--Margiana Archaeological Complex in Turkmenistan by Soviet archeologist Viktor Sarianidi, including horse-drawn carts (mentioned in the Rig Veda), cast new light on India's past. Wood also attempts to re-create soma, an ancient drink recorded in the Rig Veda.
