On Kola Island, the drought had meant that money had ceased to be of value. Everything was measured against water which was used to buy and sell. There, young orphan Omar receives from the hands of a strange messenger in the form of a bear, an almost undecipherable letter in which the famous Treasure of Kola is mentioned. And so, that day, a bear, a messenger and a boy set out on an adventure that will take them through the four regions of Kola Island, hardly suspecting that they are being followed by a menacing shadow.
