Sea Hunt

Sea Hunt follows Mike Nelson, a former U.S. Navy frogman who earns his living as a professional diver and underwater troubleshooter. Working off the coast and across far-flung waters, he takes on risky salvage jobs, search-and-rescue missions, and investigations that pull him into smuggling schemes, sunken secrets, and desperate pleas for help. Each episode blends tense action above the waves with extended underwater sequences, highlighting the hazards of the deep and the ingenuity needed to survive them.

Set in the late 1950s, Sea Hunt centers on Mike Nelson, an experienced ex-Navy diver who now operates as an independent contractor for anyone with a job too dangerous for ordinary crews. One week he is hired to locate a missing person or recover crucial cargo from a wreck; the next he is drawn into protecting innocent people from criminals who use the sea as cover. Nelson navigates treacherous currents, failing equipment, and the ever-present risk of running out of air, while also dealing with deception and violence topside. The series moves between harbors, coastal towns, and open water, building suspense through practical problem-solving and high-stakes underwater work. With each assignment, Nelson’s professionalism and calm courage turn perilous missions into hard-won victories.
