The British discover a potential escape route through the boarded-up camp theatre. Despite protest from Mohn, the Kommandant agrees to Colonel Preston's request to have the theatre, which was used for an escape the previous year, reopened. Ulmann is enthusiastic about the idea, hoping to catch the prisoners in the act of plotting to escape. While the prisoners manage to get around Ulmann's heightened security measures, they encounter an unforeseen problem when the French have the same idea of using the safe route out of the theatre. However, the attempts go ahead.
