The allied armies get closer to Colditz and there is unrest when a death sentence is passed against one of the prisoners. Colonel Preston starts to mobilise the British in preparation for a possible revolt. The kommandant receives some terrible news – and a visit from the SS.
A trio of Americans arrive at Colditz to join the solitary US inmate, Jim Phipps – but his suspicions are aroused when he sees the newcomers getting access to American newspapers and better provisions and despite the fact that there is a familiar face, the British wonder if in fact they are housing a German trained fifth column.
Colditz is a British television series co-produced by the BBC and Universal Studios and screened between 1972 and 1974. The series deals with Allied prisoners of war imprisoned at the supposedly escape-proof Colditz Castle when designated Oflag IV-C during World War II, and their many attempts to escape captivity, as well as the relationships formed between the various nationalities and their German captors.
