The Rat Patrol

A young French Resistance fighter--Michele--survives the Patrol's quick assault on a small German convoy. She explains that she was captured during her groups' attempt to stop the convoy which carries radar equipment. However Michele is a double agent and is going to deliver the Patrol to her lover--a German officer. She talks the Patrol into going to the radar base (supposedly to destroy it). She turns them over to him and, in the end, when the Patrol manages to escape--and blow up the radar base--he is killed.
