The Yesterday Machine
Taking place in a small town in Texas (speculated as Denton, Texas), Margie De Mar, a young cheerleader, and Howie Ellison, her boyfriend in a Letterman sweater, are stranded in the woods after their car breaks down. After ignoring a "Warning" sign while looking for refuge, they spot a farmhouse where "There's A Light." They encounter Dr. Earnest Von Hauser, a Nazi scientist who is doing time travel experiments using his theories of "Superspectronic Relativity and the Minus Ray." His goal is to alter the results of World War II, and to resurrect Adolf Hitler.
