May 1944. When spy Elisabeth de Mornay, code name Cécile, notices a coded transmission from an agent in the field does not bear his usual signature, she suspects his cover has been blown, something that is happening with increasing frequency. With the situation in occupied France worsening and growing fears that the resistance has been compromised, Cécile is ordered behind enemy lines.
Having rendezvoused with her fellow agents, Léonie and Dominique, together they have one mission: help the resistance destabilize German operations to pave the way for the Normandy landings.
But the life of a spy is never straightforward, and the in-fighting within the resistance makes knowing who to trust ever more difficult. With their lives on the line, all three women will have to make decisions that could cost them everything, for not all their enemies are German.
