Dale "Mac" McKussic (Mel Gibson) is a former drug dealer trying to go straight. His close friend Nick Frescia (Kurt Russell) is a Detective Lieutenant with the Los Angeles County Sheriff's Department who, in spite of their long-term relationship going back to high school, is duty-bound to bring Mac to justice if he is selling drugs again, as Drug Enforcement Administration Agent Hal Maguire (J. T. Walsh) believes to be the case.
