After a hair stylist for a television show is murdered, Brenda and the squad must wade through a history of domestic violence and secret addresses to find the murderer. Brenda also has to deal with her parents (guest stars Frances Sternhagen and Barry Corbin), who have decided to pay a surprise visit in the RV on the way to Alaska. And Brenda's father, Clay, is determined to drop less-than-subtle hints about when they can expect Brenda and Fritz to finally tie the knot.
