Top-notch action sequences and exciting stunt work highlight this fast-moving thriller. John Kruger (Arnold Schwarzenegger) is a top agent in the U.S. Marshalls' Witness Protection Program; it's his job to "erase" the pasts of Federal witnesses under his watch and deal with anyone who tries to hurt them. Kruger's latest assignment is to protect Lee Cullen (Vanessa Williams), who while working for a major weapons manufacturing firm discovered evidence that the company was selling new, high-tech weapons to intentional terrorists groups with the cooperation of a faction of enemy agents within the United States government. However, when Kruger discovers that the Witness Protection Program has a rat in the house -- and that rat is his boss, U.S. Marshall Robert Deguerin (James Caan) -- Kruger has to guard his own life while trying to protect Lee's. The supporting cast is highlighted by James Coburn, Robert Pastorelli, and James Cromwell.
