Человек-амфибия

Argentinean doctor Salvator, a scientist and a maverick surgeon, gives his son, Ichthyander, a life-saving transplant: a set of shark gills. The experiment is a success but it limits the young man's ability to interact with the world outside his ocean environment. He has to spend much of his time in water. Pedro Zurita, a local pearl gatherer, learns about Ichthyander and tries to exploit the boy's superhuman diving abilities.
