Although presented as a World War Two thriller this film is intended as crude propoganda and in this I am sure at the time it was effective. The film concerns wounded war hero stranded ill at a sanatorium run by undercover homicidal nazi's. They try to suppress him getting vital war information through by making others think he is mad and his taking the blame for vicious strangulations one of them performs. In this respect nazi's are shown as evil, plotters with no morals and a murderous, even perverted personality.
The portrayals are salacious and show the nazi's delighting in their evil, while this was popular during the war now it lookings old fashioned, even shocking in its crude depiction. Indeed the daughter of a general is killed and by the end of the film, the genral seems to have forgotten all about it once the nazi's have been caught. However the film is made at a pace and has a quaint view of England during the war, all the English having as outlandish accents as the germans. It's fairly enjoyable and seems to relish the horror touches in the murders "'er 'ead was almost twisted right off" is a phrase used a number of times ghoulishly. Mention should go to John Abbot as the killer nazi who acts in the kind of crazed way rarely found outside of Martin Kosleck films. Overall it's enjoyable but crude by today's standards. 7/10.
