A group of Nazi sympathizers of various nationalities board a submarine at Oslo on a secret mission to land in South America where it is planned that Hitler and the Third Reich will rise up once again. On navigating the English Channel, one of the party gets injured – Florence Marly (Mdm Garosi). She needs a doctor and it's the one thing that has been overlooked on this journey. So, they stop over in France and kidnap one – Henri Vidal (Guilbert). They resume their journey with the new arrival who realizes that his life is in danger as he now knows too much – he has to survive by making himself indispensable to the gang.
The whole story is pretty much set aboard the submarine. It's a novel setting and provides the necessary claustrophobic atmosphere as we wonder how and when our doctor hero is going to make his escape. Other characters don't fare too well when deciding to break free from the clutches of evil Jo Dest (Forster). By the way, this Dest character is a cartoon character Nazi who has a blatant homosexual arrangement with his young muscleman as played by Michel Auclair (Willy). Dest's male bitch is even given the name 'Willy' so that you are under no doubt that they like playing with each other's willies.
