When Austin police officer Zoe Barrow fatally shoots twenty-five-year-old Jesse Garcia during a standoff, Internal Affairs has some hard questions -- because the dead perp also happens to be the guy who put a bullet in Zoe's husband and left him a vegetable. Assigned to desk duty until she's cleared of any vendetta, Zoe tries to piece together a series of strange and violent new twists that will make or break her career.

One of her snitches, a local prostitute, is murdered and Zoe finds a strange connection to another unofficial case: a friend of her husband's who thinks his wife has hired someone -- a cop -- to kill him. Soon, threats from Garcia's uncle, another brutal murder and a sobering link to police corruption put Zoe in the line of fire, fighting to save her badge, her honor and her skin.
