On a dark and stormy night, America's favorite mystery writer/amateur sleuth Jessica Fletcher takes a bus ride with a bevy of guest stars. While they hole up in a roadside restaurant, a passenger gets murdered, and everyone's a suspect (except Jessica and Amos natch). Whodunnit? Whydunnit? Will Jessica figure it out, or will they all fall victim one by one? Most importantly, will they make it to the Sheriff's Conference in time for Amos to get some potato soup? Let the man have his potato soup!
