The BAU team searches for a serial killer who is preying on married couples. Also, Hotchner looks to one of the team to fill JJ's vacant role.

Things heat up as the New Directions go head to head with the Dalton Academy Warblers at Regionals. Musical performances include “Cough Syrup”, “Stand”, “Glad You Came”, “Fly/I Believe I Can Fly”, “What Doesn’t Kill You (Stronger)” and “Here’s To Us”.

John gets an unexpected request from his ex-wife just as he, Ben and Chickie are sent out as part of a maximum deployment to capture the "Canyon Rapist" (guest star THOMAS LUMBERG, JR.), a perp who has been impersonating a cop. Lydia gets re-partnered with Russell (recurring guest star RUSSELL EVERETT SCOTT) for a double-homicide case. And Sal gives his wife Susan (guest star DENISE CROSBY) a special gift to commemorate her promotion, but their night turns into a disaster when their daughter, Kimmy (guest star ANNAMARIE KENOYER) reveals Sal's affair with TV news reporter Mia Sanchez (guest star LISA VIDAL).
