During World War I, a female German super-spy (and morphine addict) known as “Fraülein Doktor” (Suzy Kendall) steals the new mustard gas formula from its French female inventor, Dr Saforet (Capucine). The Germans then use the gas to great effect against the Allies in the trenches.
Fraülein Doktor then seduces a laundryman to find out which ship Lord Kitchener will be sailing on to Russia, and when it will sail. She then helps a German U-boat to sink HMS Hampshire outside Scapa Flow with Kitchener on it, taking his life.
For her next assignment, (obtaining Allied defence plans for a German attack in Belgium) she poses as a Spanish contessa and travels with Spanish nurses on a hospital train to the Allied front (assisted by German agents who impersonate Belgian officers to penetrate Belgium Army headquarters and steal the plans).
The nightmarish climactic battlefield scenes depicting the horror of a mustard gas slaughter – with German cavalry emerging through the gas cloud on horses who are wearing protective clothing and gasmasks – will stay with you.
This Italian and Yugoslav co-production was loosely based on the life of Elsbeth Schragmüller.
