Nii from the Gold Coast of Africa is thrown into a sea full of sharks when he stows away on a ship. He is rescued by a magic rainbow fish which takes him to the kingdom of the Zulus. He meets Tofi and learns how to look after cows. He, in turn, teaches her how to fish in the sea. One day the rains fail to fall, the grass withers, the cows die. However, like true love... the sea never dries.
