Screenwriter Matthew Michael Carnahan adapts Prentice Earl Sanders and Bennett Cohen's 2006 novel for the silver screen to tell the tale of a brutal killing spree that rocked San Francisco, CA, and left at least 16 people dead between 1973 and 1974. Jamie Foxx stars as Sanders, one of two African-American police detectives who fought discrimination from within the police department as they went about solving the racially motivated murders. When the elusive killer was finally caught, the two dedicated policemen successfully sued the city for discrimination and Sanders was elected chief of police. ~ Jason Buchanan, All Movie Guide
