As a thick fog settles over London, Holmes and Watson break into a spy’s home on a quiet street in Kensington. There, they discover a series of cryptic messages, and the true nature of the conspiracy comes to light.

In a final bid to get the Bruce-Partington plans back before they fall into enemy hands, Holmes sets a dangerous trap for the traitors.
