Irwin Allen attempts to recapture the phenomenal success of his The Poseidon Adventure by virtually re-capping the original storyline with a new set of faces. The luxury liner, turned upside down after being smashed by a tidal wave, takes about a few opening seconds of screen time. After that the film becomes a treasure hunt aboard the overturned vessel between salvage tug operators Mike Turner (Michael Caine), Wilbur Hubbard (Karl Malden), and Celeste Whitman (Sally Field) who are searching for cool, wet cash and Filthy McNasty bad guy Stefan Svevo (Telly Savalas) who is looking for a stash of hidden plutonium.
