Its up to the Captain and Sarah to reach the doctor and seize this weaponknown as the Bleedingbefore the Nazis can use it to murder thousands. Joining them on their journey, in of the guise of a servant, is Clementine, a half-German, half-Senegalese girl, whose wit and ferocity are a perfect match for Sarahs.
