This science fiction thriller was inspired by a mythical real-life event, the WWII era disappearance of an entire naval vessel during a radar-cloaking test. In 1943, David Herdeg Michael Pare and Jim Parker Bobby DiCicco are sailors stationed aboard a Virginia battleship. Their vessel is undergoing an experiment conducted by brilliant scientist Dr. Longstreeet (Eric Christmas), who is attempting to render Allied craft invisible to radar. The ship becomes briefly invisible, but the test is a disaster and most of the crew are horribly killed. However, two crewmen are missing. In 1984, Herdeg and Parker emerge in the Nevada desert, having somehow traveled through time. Longstreet, still trying to perfect the device after 40 years, is running another experiment that pulls the missing sailors into the present. Realizing what's occurred, Herdeg and Parker flee, fearing for their lives. Fugitives, they befriend a skeptical modern woman, Alison Hayes (Nancy Allen). An effect of time pulls Parker back into 1943, leading to a bizarre reunion between Herdeg, still trapped in the future, and Parker, now a senior citizen. The film was followed by a sequel nine years later.
