The arrival of one of Britain's top fighter pilots - Squadron Leader Tony Shaw causes disagreements in the German staff as to how to handle such a specialist prisoner – but Shaw turns out to be more interested in studying English literature with fellow inmate James Porteous – however will Shaw settle down to a life of study while Simon Carter is badgering him to become the focal head of escapes?
A new second-in-command is appointed to Colditz, but Major Mohn – a distinguished and much decorated soldier is determined to continue fight the war inside Colditz and Simon Carter whose broken ankle is not mending is prepared to meet him head on, but a psychological battle between them has consequences for the Kommandant and Colonel Preston, who is forced to appoint a new escape officer.
Simon gets an idea to hide prisoners to effect a dummy escape which would then take pressure off any genuine escape, but Major Mohn is highly suspicious and starts to impose further restrictions on the prisoners and this impacts Simon's plan and puts the lives of 2 men in danger.
