As he travels through the spectacular landscapes of tea country, arid plains and urban mayhem, Monty's quest to gain insight into India's own epic cultural journey leads him from the majestic tomb gardens of the Mughal emperors and the pleasure gardens of the Hindu Maharajahs, to the quaintly nostalgic heritage of the British tea planters and a unique rock and sculpture garden little known in the west.
