Irwin Winkler's paranoid thriller focuses on a high-tech nightmare, as a computer programmer finds herself on the run from an unknown enemy dedicated to ruining her life by digital means. Sandra Bullock stars as Angela Bennett, a programmer who unwittingly comes into possession of software that allows access to secret government information. At first, she thinks little of it, heading off to Mexico on vacation. However, thanks to a series of odd events that culminates with the death of a close friend, Angela starts to suspect she may be in danger. This fear is confirmed when she returns to America to find that her identity has been erased, with police computers showing her as a wanted criminal. She soon realizes that a group of evil conspirators are after the program, and she sets out to clear her name and keep the program from falling into the wrong hands. The central concept later inspired a cable TV series.
