The war in Europe is over, the Japanese
are about to surrender after the Nagasaki bombing, but a group of
die-hard German Nazis are holding on in Shanghai, protecting an
ingenious invention of mass destruction - a cosmic ray generator that is
1000 times more deadly than the A-bomb. Col. Von Meyer is about to pass
the secret of the weapon to Col. Noyoma, as Japan is still at war, and
will use it to revenge their recent losses. However, Field Marshal Von
Runzel arrives with precise orders to the contrary: the Japanese shall
not have the secret weapon, for an underground Nazi ring is to use it
later in another attempt to destroy all the Allied Nations, and conquer
the world in a third Worl War. Von Meyer decides to create a diversion,
and to offer the Japanese scientist and officers some "evening
entertainment" at the German Officers' Club. Thaler, the female German
Officer, is to bring in a number of women - arrested on trumped up
charges at the Shanghai University - dress them up, and force them to
service the lusty Japanese officers. First, he asks for volunteers, but
only the French entertainer Yvette comes forward. The other five women
(American, English, Austalian, Russian and Mexican) stubbornly refuse.
Then he shouts at them: "I say, naturally you'll all volunteer!" The
16-year-old Australian girl finds her mother as a hard-laborer at the
club, they rejoice for a while, but knowing that her pure catholic girl
will be ravished that night, Mrs. James kills her daughter instead. Her
absence will not be missed much, as two other young women arrive, a
Chinese and a Japanese. Soon, the Germans are about to betray the
Japanese, but the American is in cahoots with an infiltrated German
officer who's really her husband (an OSS spy), the Chinese is trying to
make the others believe that Maya is an infiltrated Japanese agent,
while Lili herself is seeing a Chinese servant of the Germans in secret,
and the women are justly suspicious of Yvette - who is getting fond of
the bald-head Colonel Von Meyer... In the end, the American plot is
uncovered, the Germans and the Japanese start killing each others, and
the fugitive American and Chinese spies.
