Eraser Trailer (1996)

Arnold Schwarzenegger is elite federal marshal John Kruger, who works for the Federal Witness Security Protection Program (WITSEC). Kruger must do anything to keep witnesses he protects safe. When Lee Cullen (Vanessa Williams) sees what she is not meant to, a powerful force wants her dead. Cullen works for a leading defense contractor - she uncovers a scheme to deliver an advanced weapon known as the rail gun into the hands of the wrong people. Marshal John Kruger must protect Cullen, as her greatest threat comes from within the government. Kruger comes up against someone of equal skill as he tries to guard Cullen against conspirators and Robert Deguerin (James Caan), his former mentor. Kruger himself comes under suspicion and sets out to prove his innocence to Bellor (James Coburn), the head of the Witness Protection Program.
