Riddled with plot holes
This was a potentially promising film with a topical subject and a lot of talent on board - director Costa-Gavras and stars Debra Winger, Tom Berenger, John Heard - but Joe Eszterhas's screenplay really sabotages its chances.
Why would the FBI send such a green and unprofessional agent as Debra Winger's character on such a dangerous mission for her very first undercover assignment? How could she be so blinded by emotion to fall in love with her target on her first undercover assignment? And what do the FBI bosses do to Winger when they realize she's caught up in a right-wing conspiracy to overthrow the government? Why, they do the obvious thing, of course: deny her any backup, bully her when she tells them she's scared for her life, and after she witnesses a cold-blooded racist murder, they don't even do any forensic or ballistics work because "We'll never find the body". More than that, I found it tough to believe that Winger's character could still feel any tenderness or sexual attraction towards Berenger after finding out what a psychotic monster he was. Plus she does so many naive and foolish things, like making secret phone calls and stealing the pivotal computer printout, that it would be impossible for Berenger not to notice her deceptions sooner.
All in all, a wasted opportunity.
