Vijay and Durga have no idea what they are in for when they accompany their amateur archaeologist grandfather to the excavation site of the Indus Valley civilization. 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 civilizations of the world.
