Pardee, the newly appointed port warden of Los Angeles harbour, a
strict disciplinarian who does everything "by the book."
The next day, Gib is conferring with his assistant, Marsh Walker,
who served with Gib in the Navy and is confined to a wheelchair. Later,
Marsh's wife Kay comes to take him to an anniversary dinner at the
nearby White Swan Café. Meanwhile, at the café, a ship's
radio operator approaches Marsh and wants to speak to the harbour
warden, as he is troubled by the fact that his captain has been sending
private radio messages.
Some time later, when Marsh is at home with his wife and children,
Gib phones to say that the harbour police have found the murdered
body of a man, dressed in a radio operator's uniform. Later, Snyder
warns Gib and Marsh that they must leave immediately as there is an
atomic bomb aboard his ship and that it will be detonated electronically
from a distant point. How ever, a headline in a Los Angeles newspaper
informs the general public that officials have explained that the
offshore explosion was simply an experiment to alert coastal cities
to potential dangers.
