In Fifties Los Angeles, Ed Exley (Guy Pearce), Bud White (Russell Crowe) & Jack Vincennes (Kevin Spacey) are three very different cops. Ed is ambitious & incorruptible, Bud takes pleasure in beating up wrong-doers, & Jack works as technical advisor to the television show ' Badge of Honour'. Ed earns the enmity of Bud & Jack when he testifies that they were involved in the beating of a group of Mexicans in police custody, but all three men become involved after a mass-murder takes place at the Nite Owl cafe. Initially, it seems that a group of black junkies are responsible, but further investigation leads to evidence of blackmail, prostitution & a police cover-up in high places. Kim Basinger won an Oscar for Best Supporting Actress.
