Joan Cusack will guest-star on Law & Order: SVU, TVGuide.com has learned exclusively.
The 47-year-old Oscar-nominated actress will play the mother of a girl who disappeared some years earlier. When her other daughter also goes missing, she becomes the focus of an investigation.
Cusack's appearance coincides with the introduction of Erik Weber (Henry Ian Cusick),a graphic designer who woos Detective Olivia Benson.
