Colditz gets a new senior British officer, Colonel Preston (Jack Hedley). (The previous senior British officer, Major Donaldson is referred to in this episode but never seen). On his arrival he witnesses a futile escape attempt by Flight Lieutenant Carter and when the Kommandant meets him, he believes Preston is a man of honour who he can deal with . The colonel's new orders that seem to be appeasing the Germans cause conflict and dissension in the ranks, but there is method in the colonel's madness, which could come unstuck when a Polish officer decides to escape.
