Combat Hospital

Two new doctors arrive at the NATO Role 3 Medical Unit at Kandahar Airfield and must face rocket attacks and waves of wounded soldiers and civilians within their first 48 hours.

A sick soldier is brought in, and the bacteria infecting him quickly spreads to others in the hospital, which forces a quarantine.

Rebecca depletes the blood supply while she and Bobby operate on a soldier with severe gunshot wounds, forcing Colonel Marks to call for a walking blood bank.

Simon hitches a helicopter ride to his farm; Rebecca must perform emergency neurosurgery on a patient; Bobby and Pedersen try to help an Air Force officer with his insomnia.

Mark receives a worrisome call from home and confides in Pedersen; Rebecca and Bobby participate in Pederson's group therapy session, leaving Rebecca feeling vulnerable when she over-shares.

Rebecca reveals to Simon that she is jealous of Bobby's recent success and discusses her feelings with Pedersen; when Nurse Suzy Chao is assigned to help Bobby with his research, she develops a crush on him.
