"Lottie Mason" (Theresa Russell) is a vice cop who works during the night as an undercover prostitute. Her boss, "Lt. Joe Morgan" (George Dzundza) is corrupt and makes life as tough as possible for her because she won't sleep with him. Meanwhile, the Assistant District Attorney, "Stan" (Jeff Fahey) is trying to make a case against a dangerous drug dealer named "Tony Peron" (Shawn Elliott) and needs an attractive undercover agent to entice a witness to testify against him. Naturally, Lottie agrees to do the job. Now, rather than revealing the entire plot I will just say that things begin to go haywire soon afterward. As far as the overall film is concerned I thought Theresa Russell looked absolutely gorgeous. Unfortunately, I felt that the relationship between her and "Stan" lacked chemistry. Along with that, I also thought that the first half of the film was much too slow developing and didn't really start to pick up any steam until the final 30 minutes or so. In short, it wasn't a bad movie but given the talent available it certainly could have been better. I give it an average rating.

A female undercover cop, overworked, exhausted and ready for a break, gets seduced one night into a short walk on the wild side, but it may prove to be her undoing. Well-directed cop thriller isn't a blockbuster, nor is it capable of really expanding its perimeters on the basis of a slight budget, but filmmaker Sondra Locke gets fine performances from her cast, particularly Theresa Russell, exuding palpable street-glamor in the lead, and handsome George Dzundza as her lieutenant. I have never been an admirer of creepy-eyed Jeff Fahey's work (he always seems hyped up for little purpose), but he isn't too distracting here. Little-seen picture is perfect late-night TV fodder; nothing overly substantial or imaginative, but tightly-wound and involving. **1/2 from ****

In "Impulse" a female undercover cop (Russell) stings johns, gets involved with a drug bust, and...yada yada yada. A typical and ordinary Hollywood crime genre product with Russell and Fahey sharing the spotlight, "Impulse" is a par flick, shot entirely in and around L.A., with the usual ugly bad guys, macho cops, chases, shootouts, etc. with the emphasis on drama over action. Nothing new here. Best enjoyed with your favorite beverage and munchies.

Intriguing but slow moving thriller about an undercover woman vice cop who yields to the temptation of sex and money. Theresa Russell, who reminds me of a younger Kathleen Turner, provides a very capable performance as a woman who lets her undercover identity take over from her. Fine acting by the cast all around, but the turgid pace of the entire movie puts a dampener on it all. Watch it if you have the patience.
