Just days after the birth of baby elephant Tutu, human hunters arrive late at night and decimate the herd. Faced with the loss of their family, Tutu and Zef set off across the African plain in search of a future. At a nearby watering hole, Tutu encounters a flamboyant flamingo, who leads him to believe that he will find his lost mother at the end of the rainbow. Though Zef knows better, he can only hope that a new elephant herd will eventually take them in, and the two siblings continue their search. A chimp and giraffe soon join them, orphans as well, and though rivalries emerge, the foursome trek on across landscape both magnificent and treacherous.
