In the 50's, in Los Angeles, the LAPD is corrupt and violent, When the rookie Sgt. Ed Exley is assigned to be responsible for the precinct in the Christmas Night, he denounces many fellow officers for the beating on six Mexican guys in the precinct and is promoted to lieutenant. The violent Detective Bud White, disturbed by the death of his partner Richard 'Dick' Stensland, investigates the Night Owl massacre, where Stensland was murdered. The celebrity Jack Vincennes also investigates and discovers secrets about the murder in the middle of several cases of corruption and blackmail. Exley and White look for the truth that may take down the LAPD and their Captain Dudley Smith.—Claudio Carvalho, Rio de Janeiro, Brazil
