An evil scientist known as "Mr. M." uses a drug he has developed called "hypnotreme" to help steal submarine equipment. Federal agent Grant Farrell is dispatched to find the mysterious villain and stop his nefarious plans.
At the very beginning, during the credits, the shadow silhouettes are of Rondo Hatton, Basil Rathbone and Nigel Bruce. From the movie The Brute Man (1946) and The Pearl of Death (1944), a Sherlock Holmes movie.
Agent Grant Farrell:
Mr. M is making it harder to get a slab in the morgue than a room in the hotel.
Derek Lamont: The papers are calling him the Mysterious Mr. M now.
Agent Grant Farrell: Yeah, by letting us know it's our job to take the mystery out of it.
In Chapter 4, "The Second Trap", the device placed on the bookshelf to eavesdrop has the ON/OFF switch set to OFF yet works fine.
