Laleh and Myung are sisters, sole keepers of the vast and majestic whale of babel - a kind of universe where chambers of different worlds keep getting created. They know Great Wisa is their creator. They listen to the whale song- the ever present and ever changing one, make notes of newly discovered chambers in heart shaped leaves and keep exploring and documenting the birth and discovery of chambers. They are the only people they know, but Myung wonders about what if there are others. She wants to go outside the Whale.
