Impulse (1990)

Theresa Russell plays a cop working undercover for vice, posing as a prostitute to entice men who then get nicked. She likes it, discovering that the more her job makes her feel restricted, the more the danger makes her feel alive. She begins to wonder what it would be like to play her role for real.
It's not the character study I was hoping for. It never goes deep enough into her psyche or even into her private life for that. She ought to be complex, filled with conflict, but instead comes across as straightforwardly bored.
About one hour into the running time a dramatic shift in focus occurs, leading us into a different kind of drama, but it too only manages to show the surface of the depths it could've taken us. Oh, well, it could've been worse.
