Law & Order: SVU will be doing things a little differently in an upcoming episode.

The long-running NBC drama has tapped Big Love grad Melora Walters and Kingdom alum Joanna Going for an episode that breaks from the traditional Law & Order structure and instead plays as one long interview scene between Benson (Mariska Hargitay) and a woman who believes she was raped.

Walters plays the suspected victim, Laurel Linwood, who knows she was raped but can't remember what happened the night before. As the trauma recedes and details start to emerge, Benson uses every tactic she can think of to get the full story. Going will play Laurel's sister, Leah, who is brought in to help fill in the blanks.

Titled "Something Happened," the episode is set to air Wednesday, Nov. 29.

Walters, whose other credits include Cold Mountain, The Butterfly Effect and Dead Poets Society, is repped by Don Buchwald and Associates, Media Vision Artists, Shelter Entertainment Group and Jackoway Tyerman.

In addition to Kingdom, Going's credits include House of Cards and Mad Men. She is repped by AKA Talent and Vanguard Entertainment Group.

The duo join recent season 19 guest stars including Brooke Shields and Will Chase.

Law & Order: SVU airs Wednesdays at 9 p.m. ET/PT on NBC.
