After the stabbing death of a woman who was apparently killed by someone wearing a Ninja outfit, Brenda and the squad soon realize they might have a bigger case on their hands than they thought. A detective from El Paso, Texas (guest star Xander Berkeley), where a similar crime occurred, comes to LA to help in the investigation, but his primary interest is in bringing the killer back to Texas to face the death penalty. Meanwhile, Brenda's father, Clay (guest star Barry Corbin), arrives to take her niece, Charlie, home to Atlanta.
