In 1939, Sakura Nishi is a young army nurse who is sent to the field hospitals in China during the Sino-Japanese war. She has to assist the surgeon Dr. Okabe with an incredible number of amputations. In the crowded wards, she gives sympathy to some of the soldiers, including sexually servicing one who has lost both arms and has no hope of returning home. She falls in love with Dr. Okabe, and follows him to the front, even though he is impotent from his morphine addiction.
As the Chinese move closer and surround the field hospital, the film climaxes with a brutal every-man-for-himself battle that's as graphic and disturbing as anything that Stephen Spielberg or Clint Eastwood has ever dreamed up. Little will be left but buckets full of amputated arms and legs. Red Angel is one of the more powerful anti-war films you'll ever see.
