Synopsis
Mike Nelson (Bridges) is a free-lance scuba diver who has various adventures. Traveling on his boat the Argonaut, Nelson outmaneuvers villains, salvages everything from a bicycle to a nuclear missile, rescues children trapped in a flooded cave, and even a dog. In the pilot episode, Mike rescues a downed Navy pilot from his sunken jet. Since no dialogue was possible during the underwater sequences, Bridges provided voice-over narration for all the installments.
At the end of each episode, Bridges would appear as himself to deliver a brief comment. These comments sometimes included a plea to viewers to understand and protect the marine environment, along with gems of wisdom from Bridges' own experiences.
