The 918th is temporarily reassigned to a newly liberated airbase in Italy which is still perilously close to the battle front as well as a town with some residents who are still loyal to the Germans. The commander of the base, Col. Yates, happens to be a former chief of the 918th who was relieved after a series of brutal, ineffective missions. He has grown lax and allowed security to deteriorate to the point that the Germans are able to inflict serious damage with the help of intelligence from the collaborators in the town. When Gallagher dresses him down and takes charge, Yates retreats to his Italian countess lover for emotional support, without realizing she may be part of the spy ring. (thetvdb.com)
