A rip roaring Sexton Blake adventure, don't expect half measures!
An explosion at a mine causes the owner (Julien Mitchell) to sack the manager (Dennis Price), his daughter's (Pamela Stirling) beau. The owner is being blackmailed by his secretary. The owner is murdered, suspicion falls on the ex-manager but Sexton Blake (David Farrar) is called in to investigate. He begins to unravel a complicated plot which eventually leads to Nazi fifth columnists in their underground lair.
This isn't a subtle film but Sexton Blake adventures were very much Boy's Own adventures which were all about daring do and death defying action rather than careful investigation. There is probably a little too much adventure packed into this film, at times it is hard to follow what is going on though it all leads up to the expected final battle. It is nonsense of course but i loved it, Sexton Blake adventures were my great-grandfather's favourite so i guess it's in the blood!
