The clues are in, the chase is on, and the case of the century is about to break wide open in Disney's greatest little mystery in history. Come along on a journey through the cobblestone streets of 1897 London, where some suspicious "mousechief" is the suspenseful start to this thrilling musical adventure. Olivia, the brave daughter of a beloved toy maker, turns to Basil of Baker Street for help with her father's disappearance. Basil's jolly assistant, Dr. Dawson, and loyal dog Toby lend a paw—and nose—as they search for clues through their charming miniature world. The final chase leads to Professor Ratigan (Vincent Price), a hard-hearted criminal. Can Basil outwit Ratigan to save Olivia's father and all of Mousedom? Contains tobacco depictions.
