The year is 1961. Honeymoon couple Norm and Luann Weiner head for Niagara Falls for their dream vacation, never dreaming they would drive straight into the clutches of an alien invasion force bent on stealing the Falls...or that they would meet a group of ghosts who live beneath Niagara (daredevils who died in barrels, fell of tightropes etc.) who enlist our couple to save their watery grave and...the very Earth itself!!
