Brenda and Fritz's wedding is only a day away, but both of them have their minds on their jobs more 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 robbery and murder at an escort service. With Brenda's parents (guest stars Frances Sternhagen and Barry Corbin) and Fritz's sister (guest star Amy Sedaris) dealing with the wedding details, the question remains whether the bride and groom will actually make it to the altar.
