Test pilot Jim Darcy flies a NASA's experimental supersonic jet that crosses a time portal at Mach 6 and crashlands near his base. Out of his cockpit, he realizes the whole world is frozen into time and only his wife and he are desynchronized. The couple goes to the base to alert and find a solution. They witness the possible death of their little daughter because of a future truck accident. After observing immobile officials and technicians in their functions, they encounter a strange man stuck into this no man's land for so long that his physical appearance has changed radically and prevents them from the danger they risk if they remain in this in-between realm. Fortunately, they not only save their child with their car's safety belts but return to the present.
