Oku and his sister, Abo, live with their parents. They are stubborn children that never do what their parents tell them. One day, instead of doing the work that their mother gave them, they follow their friends to the river to swim. There, Abo is attacked by a crocodile, but she is later rescued by the villagers. Other children in the village learn a lesson from Abo and Oku's disobedience.
