The master detective Sherlock Holmes (Basil Rathbone) and his faithful cohort Dr. Watson (Nigel Bruce) are back, preserved and digitally restored in 35mm to original condition by the UCLA Film and Television Archive. This newly restored version of the classic film includes the period war bond tag and studio logo and credits from its original theatrical release. Filled with ominous shadows and interesting camera angles, the visual beauty of the film in 35mm is stunning. Sherlock Holmes and Dr. Watson journey to Canada to attend a meeting of the Royal Canadian Occult Society in Quebec. Before long, they find themselves investigating a series of gruesome murders that the locals attribute to the legendary phantom marsh monster of La Morte Rouge. But Holmes suspects a master of disguise is the real killer, who might be anyone in the village. He contrives a clever trap and courageously sets himself up to be the killer's next victim.
