The 918th is tasked with bombing a strategic target the Germans may be using as a spotter post for artillery that is blocking the Allied advance across France. Gallagher is highly disturbed, however, when he finds out the target is a monastery housing a convent occupied by nuns and refugees. He wrangles permission to personally attempt to sneak into the monastery and convince the civilians to leave before the attack, and has only 24 hours. However he runs into a resistant Reverend Mother (or Mother Superior, the leader of the convent) who refuses to abandon the historic building. Being German herself, the wily German commander cajoles her to stay, convinced the Americans will never bomb the area while she and her charges remain. Meanwhile, the 918th is on its way, ready to bomb the target. (thetvdb.com)
