College drum majorette Margie De Mar twirls her baton as boyfriend Howie Ellison, a cheerleader, tries unsuccessfully to repair his broken-down car so that they can get to a football game on time. As they walk to a farmhouse for help, they stumble upon two American Civil War Confederate soldiers. Confused and frightened, they run away, but Howie is shot. He stumbles back to the car, collapses, and is taken to hospital by a passing motorist. Margie simply disappears.
Newspaper reporter Jim Crandell is covering the shooting. At the hospital, Dr. Wilson D. Blake tells him that Howie had been struck by a minié ball fired from a Civil War-era rifled musket.
Police Lt. Partane and Det. Lasky, who are investigating, go to the nightclub where Margie's sister Sandy is singing. Partane informs her that Margie has gone missing. Sandy asks Jim to take her to the site where Margie vanished. They find nothing.
The next morning, Jim discusses the case with Partane. He tells Jim that at the end of World War II his army unit had liberated an unusual concentration camp, in which the prisoners were all young and well-fed. A nearby bombed-out building contained an electronic machine that couldn't be identified. Partane speculates that the machine had been a time travel device. The commandant of the camp, physicist Ernst Von Hauser, was never captured.
Sandy and Jim return to where Margie disappeared. Still not finding anything, they walk through an unexpected, unexplained, invisible something in a field and find themselves in 1789. Then, suddenly, they're beneath the farmhouse, in Von Hauser's lab, teleported there by a time machine which operates on the principle of "super spectronic relativity," a discovery of Von Hauser's in which light is made to travel faster than the speed of light as calculated by Albert Einstein. His plan is to bring Hitler back from wartime Germany to the present-day US so that the Führer - who will become immortal during teleportation - can forever rule the world. Von Hauser is also holding Margie captive.
Manfred, one of Von Hauser's two Nazi "assistants," takes Sandy to Margie's cell and locks her in. Jim is locked up, too. Manfred drags Margie to the lab. Didiyama, a slave from ancient Egypt, who now serves Von Hauser, brings Jim and Sandy food. But when Manfred returns and ominously approaches Sandy in the cell, Didiyama stabs him in the back. Before he dies, he manages to strangle Didiyama to death. Sandy uses his keys to free Jim from his cell. Jim picks up Manfred's pistol.
Sandy and Jim rush to the lab, where they find Von Hauser about to teleport Margie into the future - something he's never done before and isn't sure will work. Wolf, the other Nazi thug, fires a shot at Jim but misses. Jim shoots Wolf, who collapses. Jim forces Von Hauser at gunpoint to bring Margie back. She returns unhurt. But as Sandy, Margie and Jim try to escape, the not-quite-dead Wolf gets off another shot. He misses again; Jim doesn't. Jim then put several rounds into the time machine's control panel, disabling it.
By this time, Partane and Lasky are outside the farmhouse. Jim, Sandy and Margie emerge from a false grave in a cemetery. Jim tells Partane that it leads to the lab. Partane and Lasky go down, where they find Von Hauser trying to teleport himself in the still-working time machine. Von Hauser shoots at him, but Partane returns fire, apparently killing him. Von Hauser vanishes before their eyes, going somewhere and someplace else in time.
Partane destroys the time machine, thus ending the Nazi threat.
