S4, E15: Brenda and Fritz's wedding is only a day away, but both of them have their minds more on their jobs than their impending nuptials. Fritz is called to a stakeout in the hopes of finally arresting a drug lord known as El Jefe. And Brenda gets tied up in an investigation into a murder and robbery at an escort service. With Brenda's parents, Willie Ray and Clay (recurring guest stars FRANCES STERNHAGEN and BARRY CORBIN), and Fritz's sister, Claire (recurring guest star AMY SEDARIS), dealing with the wedding details, the question remains whether the bride and groom will actually make it to the altar.
