A 1987 crime film written by Dick Wolf and directed by Peter Werner, starring D. B. Sweeney, Charlie Sheen and Randy Quaid. Brad Pitt made his acting debut in this film as an uncredited extra.

The basic plotline (undercover policeman falls in love with prime suspect's sister and can't bring himself to make an arrest) is frequently cited as inspiring the film The Fast and the Furious.

When an undercover detective is gunned down while investigating a string of Porsche thefts, Lieutenant Vincent Bracey (Randy Quaid) assigns 22-year-old San Diego officer Benjamin "Benjy" Taylor (D. B. Sweeney) to infiltrate a Porsche garage suspected to be a front for the grand theft auto scheme. Benjy is chosen because of his extensive mechanical knowledge of German cars and his rookie status, which dissuades others from suspecting that he is a cop. Bracey wants Benjy to obtain evidence that millionaire playboy Ted Varrick (Charlie Sheen) is the mastermind behind the thefts and the murder of the detective.

Using the alias "Billy Ayles", Benjy moves to Los Angeles and gets a job at Technique Porsche as a mechanic. After Benjy fixes Ted's Porsche one night, the two men become close friends, and Benjy becomes romantically attached to Ted's sister Ann (Lara Harris). Benjy also discovers the presence of a rival syndicate led by Frank Martin (R. D. Call), which leads him to believe that Ted is not the prime suspect despite Bracey's insistence.

Eventually, Ted brings Benjy into his side business of stealing Porsches, with garage manager Malcolm (Bill Duke) coordinating the operations. Benjy's first few attempts at stealing cars fail miserably, with Martin's syndicate catching on and slashing his hand as a warning. While doing a job at the mall, Benjy and Ted are confronted by Martin's thugs, but they manage to lose them in a lengthy car chase. The next day, Ted goes to Technique Porsche and finds Malcolm has been murdered. In retaliation, he kills Frank at a night club.
