The tense story of the nuclear submarine Neptune which is rammed by a Norwegian freighter, plummeting 1400 feet before coming to rest on a crumbling sea-shelf. Using his untested two-man sub, a diving expert embarks upon a daring rescue attempt. Late-'70s vintage disaster flick with better-than-average performances.
