When he finds a seal cub and its mother in an isolated cave, he is surprised by the humorous movements and innocence of the cub and the dignity of its mother. Tottoi soon becomes attached to the seals, but his secret is revealed to heartless adults. In the name of preservation, a plan is developed to capture them for an aquarium. Now the dignity and pride of the wild seal are in danger.
