Lt. Eli Evans, B-17 bomber pilot, is shot down over enemy-occupied France in 1944. Surrounded by Resistance fighters, a licensed-to-kill SOE British agent, and Marxist sympathizers, Evans and his navigator must evade a ruthless Nazi manhunt if they are to survive. Resistance sympathizer Aime hates war but is forced to act with courage, risking her life for others. Engaged in ambush and sabotage, the combatants will debate broadcast talks by C. S. Lewis, heard as they listen to the BBC for coded messages from London.
