Quicktime Crash-landing on a mountain side, THE VISITOR (formally Adam MacArthur) mysteriously emerges from the wreckage of the downed craft, seemingly unhurt. His sudden appearance creates a manhunt by opposing national security departments (including the FBI, headed by Douglas Wilcox, and the NSA, headed by Colonel James Vise), each with its own agenda to find out who Adam is, how he survived, and why he returned. It appears that Adam, missing in action since World War II, is still the young man he was 50 years ago prior to disappearing into the Bermuda Triangle. Adam eludes his pursuers by finding refuge with Nadine and Tyler Walden, a single mother and her 13-year-old son.

Adam MacArthur helps repressed and banished scientist Louis Farraday realize his life-long project to conquer gravity. Chased by both the FBI and Vise, they utilize this discovery to make their escape in a vintage World War II fighter plane
