Jeremy Brett stars as the great detective Sherlock Holmes in this made-for-TV production. Holmes and his brother Mycroft (Charles Gray) must join forces when Holmes hits a snag while investigating a case -- a young man is found dead with the plans for a top-secret submarine project in his pocket, and the authorities need to know who killed him and why. "The Bruce Partington Plans" was produced for British television as part of the limited series The Return of Sherlock Holmes; the series was successful enough to merit the production of The Casebook of Sherlock Holmes two years later.
