It features Dr. Earl Herald of San Francisco's Steinhart Aquarium as he recounts a scientific expedition to collect sacred freshwater dolphins in the Amazon Basin. Earl Stannard Herald was a zoologist, ichthyologist and television presenter. In 1948, he became the director of the Steinhart Aquarium in San Francisco, California, and from 1952 to 1966, he presented the popular science television programme Science in Action.
