Beyond the Law (1993)
Between the two Hot Shots comedies, Charlie Sheen did this serious biker movie. It's based on real characters and supposedly, the real Daniel Saxon was inside this movie somewhere. This was written and directed by Larry Ferguson, who has written many great actioners.
Dan Saxon (Sheen) is a troubled cop. When he gets fired from a small Arizona town sheriffs department. An agent Conroy Price (Courtney B. Vance) recruits him to go undercover to infiltrate a drug and gun running group of outlaw bikers, led by Blood (Michael Madsen). He's befriended by a motorcycle mechanic, Virgil (Leon Rippy) who builds a bike from scratch and gives him the biker persona that he needs to get his foot in the door.
He also meets and falls in love with a pretty photojournalist, Renee Jason (Linda Fiorentino), who is doing a feature on bikers. Dan's past is encroaching on his biker lifestyle to where he's not sure what he is. He even scares Virgil away, and Renee is wondering if she made the right choice falling in love with Dan.
