Southland (season 4)

Rookies learn the ropes. Veterans burn out. Detectives take their work personally. Partners take their addictions too far. Relationships fall apart. Blood spatter patterns provide clues. With fast-moving action filmed on gangland streets and in pricey cul-de-sacs, Southland tells personal stories of men and women on both sides of the badge as they struggle to make a difference or simply survive.
