The story follows bear brothers Brumla and Brůča, who as cubs lost their mother Barbara in a fire. Brůča saw Barbara leave the burning building but never returned, leaving him with a deep wound. Years later, Brumla and Brůča meet a scientist named Šarlota, who has an amber stone identical to the one their mother had. When Šarlota is kidnapped by the Šroťák gang, Brůča notices that one of the gang's key members bears a striking resemblance to his lost mother and sings the same lullaby that Barbara sang to them as children. This discovery leads the brothers on an adventure full of secrets and conspiracies regarding their mother's identity.
