Before a big mission, Savage is injured with a piece of shrapnel by his heart and consigned to the hospital. He meets a gunner from Major Cobb's crew Sergeant Aaronson who has just seen his best friend Saul Barstein die and he looses his will to live. He and Savage form a bond. To save Savage, Dr. Kaiser calls in his mentor Dr Simon Lewis a cardiologist to operate. The aircraft carrying Lewis crashes and Lewis is killed, forcing Kaiser to operate - successfully along with a blood donation from Aaronson. Savage & Aaronson help each other recover. The big mission is to the Ruhr Valley, after which Aaronson & Ivy get married. (thetvdb.com)
