A railroad crossing. A stranded car. A beautiful blonde - unconscious. Moody scientist Jim Grayam (Jeff Hunter) rescues the lovely Lorrie (Anne Francis), only to learn that she's his boss' wife! She wants out of the marriage, but her cruel, controlling husband Cort (Dana Andrews) won't let her go. After Grayam and Lorrie embark on a torrid affair, he hatches the perfect plan: kill Cort while faking insanity to avoid a murder rap! Grayam's convincing portrayal makes everyone believe he's gone mad: the judge, the psychiatrists, and eventually even himself. In this edgy psychological thriller directed by veteran character actor and thriller specialist William Conrad (My Blood Runs Cold, Two on a Guillotine), there's method to one's madness. And you'd be crazy to miss it.

An engineer, a psychologist and several other disparate types take part in an experiment to see if people can live for extended periods of time in a city built under the ocean.
