“Twenty-Five Acts”, aired October 10, 2012 IMDB
The Law & Order franchise often fictionalizes real-world events. In this case, it alludes to the publication and popularity of the Fifty Shades trilogy, in an episode aired only 6 months after the trilogy was re-released by Vintage. (FSOG was first published May 25, 2011 by Writers Coffee Shop, and the trilogy was re-released by Vintage in April 2012.)
I thought that this episode also referenced the case of Jian Ghomeshi, a Persian-Canadian radio host and interviewer who allegedly strangled his girlfriend and excused it as consensual BDSM. However, in an odd moment of life imitating art, I found that this episode actually aired 2 years before the allegations about Ghomeshi went public in 2014.
The author of the hot new erotic novel Twenty-Five Acts, Jocelyn Paley, appears on a talk show. The host, Adam Cain, meets her for dinner, and she secretly gives him her panties under the table. They go back to his place. After some sex she initiates, he crosses the line, throws her on the bed and chokes her with a belt.
