Archie's Weird Mysteries
S01E19: Something Is Haunting Riverdale High
Midge, Dilton, and Ethel aren't exactly the most popular of kids, so no one thinks much of it when they go missing. However, when Archie is rendered invisible and untouchable by one of Dilton's inventions he finds that he must work with them to stop the haywire machine from turning Riverdale into a ghost town! Can Archie learn enough about the classmates he usually ignores to help them turn the machine off, especially when they can barely move a stack of papers?
Overview
Things are getting weird in Riverdale, home of all-American boy and high school newspaper reporter, Archie Andrews. Ever since an experiment in the high school physics lab went awry, Riverdale has become a magnet for the stuff of which “B-Movies” are made.
