Vijay and Durga have no idea what they are in for when they accompany their amateur archaeologist grand-father to the excavation site of the Indus Valley civilisation. Quite annoyed that they have to spend their holidays in a dusty dump they are hardly prepared for the amazing adventure that takes them back 3390 years to a world that they have only read about in their history books. An adventure that involves a clay whistle, a boy called Vala and his pet goat. Amar Chitra Katha presents a very special story that brings to life one of the most ancient civilisations of the world.
