Two friends in difficulty - tractor driver Peter Bumper and unemployed Seryoga Sousse - go to the Ukrainian Klondike to dig amber, trying to get rich. In search of ordinary amber stone, they accidentally find another - a rare and extremely valuable "inclusion". The boys begin real adventures, as it turns out that the leader of the amber mafia, in whose hands they fell, is hunting for this inclusion. Will the boys be able to get out alive and save the stone, if at stake is no less valuable treasure - love?
