From the beaches of Malibu to the streets of East Los Angeles, this fast moving drama takes viewers inside the lives of cops, criminals, victims and their families. In the series premiere, John Cooper (series star MICHAEL CUDLITZ), a seasoned Los Angeles police officer and his rookie trainee, Ben Sherman (series star BEN McKENZIE), respond to a call that ends in a deadly shoot-out -- and Ben is left questioning whether or not he has what it takes to become a police officer. Even though John is cool to the new recruit and his straitlaced "Beverly Hills" past, his honed insight and honest, no-nonsense advice is invaluable to the young rookie: "Look sharp, act sharp, be sharp. You do what they teach you in the academy, you will die."
