The plot of Hello Down There is: Fred Miller (Tony Randall) must prove that his new design for an underwater home is viable by convincing his family to live in it for 30 days. His son and daughter (Gary Tigerman and Kay Cole) are members of an emerging pop rock band (Richard Dreyfuss and Lou Wagner) whom they invite to live with them during the experiment. Their temporary home, which Miller dubs the "Green Onion," is 90 feet below the surface of the ocean and is filled with super-modern appliances and amenities for house-wife Vivian (Janet Leigh) all designed by Miller, and a hole in the floor providing direct access to the sea.
The group are soon joined by a live-in seal named Gladys and a pair of dolphins (Duke and Duchess) which stay close at hand and fend off unwanted sharks. They are confronted by many obstacles including a rival designer (Ken Berry) from Undersea Development Inc. who begins to cause problems for the inhabitants of the "Green Onion".[1]

The band gets its airing, and the Navy is alerted by the sounds of the music coming from the sea. As naval fleets swarm in to investigate what must surely be a Communist plot, the movie will disruptly end..
