Early May 1940. Nazi Germany launches its Blitzkrieg across Western Europe, crushing France, Belgium, and the Netherlands in a matter of weeks. As Paris falls and France surrenders, a new reality takes hold—one of occupation, fear, and collaboration.

Amid the chaos, one man makes a choice that will cost countless lives.

Harold Cole, a British soldier and career conman, refuses evacuation during the Dunkirk retreat and remains in occupied France. Posing as an intelligence officer, he infiltrates resistance networks and escape lines meant to save Allied soldiers. But behind the mask lies betrayal.

Operating in cities like Lille, Marseille, and Paris, Cole builds trust—only to destroy it. His actions lead to the arrest, torture, and death of at least 150 resistance fighters and Allied agents, many at the hands of the Gestapo, the Nazi secret police.

From fraudster to collaborator, from escape-line operative to SD informant, Cole’s story is one of deception, manipulation, and devastating consequences.
