Southland (10pm, TNT) - John desperately tries to save Hicks while facing dark truths from his own past. Also, Sammy is haunted by a lie he told, Lydia and Ruben search for a John Doe, and Ben takes his relationship with Elena to the next level (which I can only assume means he breaks up with his girlfriend so that he's not two-timing both women).

George Takei, known for playing USS Enterprise helmsman Hikaru Sulu on the original "Star Trek" television and movie series, will be the focus of a new satellite radio documentary program.
