French resistance operative Louise Desfontaines is sent to London to rendezvous with her controller. He instructs Louise to assemble a crack team to parachute behind enemy lines and rescue a British geologist, who is languishing in a French hospital. Should the Germans discover the man's true identity and torture him for vital information, the Allies would be fatally compromised. Louise dutifully selects her team including sexy showgirl Suzy, explosives expert Gaelle and working girl Jeanne, and together they cross the English Channel in search of their man.
