Sabotage

A ring of saboteurs is causing havoc in London with a series of explosive terrorist attacks. Karl Verloc is part of the group, but he maintains a cover as a kind movie theater owner. His wife is beginning to suspect something, though, and so is Scotland Yard Detective Sgt. Ted Spencer . What neither of them know, however, is that Verloc uses his wife's little brother to deliver the bombs in film canisters.
