Nick Quinn is in jail, accused of the murder of his beloved wife, Julia. The police say they found the murder weapon, with his fingerprints, in the trunk of his car. Nick is confused, grief-stricken -- and completely innocent. Then a gray-haired gentleman visits Nick in the interrogation room and offers him a talisman that allows Nick to go back in time, one hour at a time, for twelve hours. Nick has the ability to save Julia, but failure would lead to a far greater catastrophe.
