LOS ANGELES (AP) — NBC's "Law & Order: Special Victims Unit" is taking on several shades of gray.

The show's producer says Wednesday's episode dramatizes the courtroom effect of bondage novels like the best-selling "50 Shades of Grey."

Anna Chlumsky guest stars as a bondage romance author who's assaulted by a TV host, then is reluctant to press charges. Roger Bart plays the host in the episode airing at 9 p.m. EDT Wednesday.

The story explores how a sexual-assault case could be complicated by the allegation that a victim invited "rough" treatment, executive producer Warren Leight said.
