When Law & Order: SVU returns on September 23, it's bringing a trio of guest stars with it. Luke Perry (90210), Sara Gilbert (Roseanne, 24), and Julie Bowen (Ed, Lost) are all set to make appearances. Perry and Bowen play a couple accused of abusing their foster child. Gilbert is on board to play the child's biological mother.

In addition to the main foster-child abuse storyline, the premiere is going to deal with Benson's (Mariska Hartigay) attempted rape a the end of last season, as well as Fin's (Ice-T) possible transfer out of SVU. The premiere also marks the debut of the new ADA played by Michaela McManus (One Tree Hill).
