Robert DeNiro continues to lampoon his tough-guy persona with this spoof of buddy cop movies that teams him with comic co-star Eddie Murphy. DeNiro is L.A.P.D. detective Mitch Preston, a gruff, no-nonsense 28-year veteran whose bust of a drug gang is botched one night by Trey Sellars (Murphy), a bumbling patrolman who's really a frustrated actor at heart. When Mitch's aggravation is captured by a television news crew, he fires his gun in their direction and becomes an instant media celebrity, while earning himself a temporary suspension at work. After his fame draws the attention of network TV producer Chase Renzi (Rene Russo), Mitch is soon informed that the only way he can get back to work is to allow a production crew to trail him on the job for a new cop reality series called "Showtime". In order to make the taciturn lawman more palatable to the viewing public, he's paired with the camera-friendly, fast-talking Trey. The new partners drive each other crazy, but their mismatched sensibilities make for great TV, while their newfound fame has its advantages in getting them back on the trail of those escaped drug dealers, who possess a powerful new weapon. Showtime co-stars Frankie Faison and William Shatner, who sends up his own TV cop role in T.J. Hooker.
