After witnessing an eerie glow in the sky, Wishbone begins to worry about aliens landing on Earth, especially when he hears a strange humming noise in the neighborhood.
Joe Talbot, filling in at "The Oakdale Chronicle" when the entire staff comes down with the flu, calls on Wishbone for help when a red-hot case breaks right under his nose.
