Old Rivalries, New Secrets, and Fresh Blood in L.A.'s Southland

Reeling from heart-aching losses, newly sober investigative journalist Birdie Keane immerses herself in wrapping up a famous cold case, the Paige Street murder. The newspaper feature creates a maelstrom of unwelcome scrutiny on her close-knit Irish cop family. The Keane clan, still struggling to escape the stigma of having a dirty cop in their ranks, has a few secrets better left alone.

Birdie's story also catches the attention of a serial killer who leaves a bloody message at each crime scene. She teams up with her cousin, hard-living homicide detective Thom Keane, himself the focus of an investigation, to catch the killer. The cousins have much to lose, professionally and personally, as they try to solve the case and bring the killing spree to a halt.
