Fourteen-year-old Fi Phillips investigated the paranormal while touring the country in a bus with her widowed rock-star mom and her skeptical brother, Jack. Henry Winkler was among the producers of this family-oriented adventure, which nicely mixed the creepiness of 'The X-Files' with the wholesomeness of 'The Partridge Family.' At the beginning of Season 3, Fi passed the job of case cracker to a songbird named Annie.
