Season 4 of Southland is set to debut January 17th with Episode 1.04: Wednesday. This all-new episode finds John Cooper (Michael Cudlitz) returning to duty after recovering from back surgery. He meets his new partner, Officer Jessica Tang (special guest star Lucy Liu), a tough and disciplined cop with her own set of baggage from working the streets. Lydia (Regina King), whose new partner is Ruben Robinson (guest star Dorian Missick), can't seem to escape helping a former CI who won't stay in safety. Meanwhile, Ben (Ben McKenzie), Sammy (Shawn Hatosy ) and Dewey (C. Thomas Howell) chase an armed man into an elementary school, while Ben bumps heads with an intense street cop (guest star Lou Diamond Phillips) whose cynical attitude is affecting their work.
