England, at the start of World War Two. Mysterious wireless broadcasts, apparently from Nazi Germany are heard over the BBC. They warn of acts of terror in England, just before they take place. Baffled, the Defense Committee call in Sherlock Holmes.
Unfortunately the movie Sherlock Holmes and the Voice of Terror is not yet available on HBO Max.
