12:01 on AllMovie

Based on a story by Richard Lupoff (a short filmization of the same story earned an Oscar nomination for 1990), 12:01 centers on a member of the personnel department in a science lab, who discovers that the world has become somehow trapped in a strange time warp that causes the same 24-hour period to repeat itself. During the course of that endlessly repeated day, Barry Thomas, the only one who seems to be aware of what's happening, must somehow figure out how to put time back on its normal course and solve the murder of a physicist, Lisa Fredricks (Helen Slater) with whom he is infatuated.
