IMDb
A pair of caught French escapers bring back information that would greatly aid any escape attempt and Simon starts to devise a way of communicating with London – but it depends on his wife Cathy being able to understand a complicated code. At the same time a new prisoner – Page – seems to be a bit vague on facts and there is suspicion that he may not be all he appears to be.
