She provided the inspiration for the character of Mademoiselle Lise Lundi in the 2009 film Korkoro, written and directed by Tony Gatlif.

[4] As a Resistance worker in occupied France, Lundy began supplying forged official documents to escapees from the camp at Bazancourt and to Jewish families.

[4][5] She assisted the Communist Marcel Nautré,[4] and others involved in the Possum network,[3] in avoiding detection by the authorities, as well as providing shelter at her brother Georges' farm for Free French fighters parachuted into the region.

[4][5][6] During the interrogation, to protect her brothers and sister (René, Lucien, Georges and Berthe) who were also working for the resistance, she pretended to be an only child.

[3][6] Yvette Lundy was freed from Schlieben by the Red Army on 20[8] or 21[5] April 1945 and, after a march of some 200 kilometres to Halle, was flown back to France, arriving at le Bourget on 8 May 1945.
