In occupied France, a convicted thief and murderer escapes the guillotine when a bombing raid strikes the prison, but is quickly re-captured by the inspector of the Surete responsible for his original arrest. Fearing the guillotine more than his actual death, the convict inveigles the inspector to help him with a plan to rescue 100 Frenchmen taken by the Gestapo following an act of sabotage: he will confess to being the saboteur and allow himself to be executed by firing squad, the Gestapo's method of execution, thus freeing the 100 men.
