Fairly interesting movie about an undercover policewoman which unfortunately gets muddled. As the story tries to cover too much ground that in the end leaves everyone watching confused and unconcerned about what it's trying to tell them.
Trying to mix big time drug dealers and protected witnesses who the DA is trying to get to testify against their former associates, the mob, with an obsessive and corrupt police officer. Together with an undercover policewoman who has enough problems outside as well as inside the police department doesn't jell together in this very complicated and confusing movie.
Besides all the negative things one can say about the movie "Impulse" the one very positive thing about the film is the appearance and acting of it's beautiful and talented star Teresa Russell. Teresa makes you, in many cases, forget the plot holes and inconsistencies of the movie just by watching her whenever she's on the screen.
