Law & Order: SVU Season 21 Episode 17 takes a deep dive into the world of professional ballet.

When the choreographer yells at a troupe of young ballerinas, one girl, Deliah, goes in a back room to make out with her boyfriend, only to find out that the encounter was filmed and put on a porn site. Deliah loses her job and goes to SVU for help getting rid of the video, but becomes uncooperative when she finds out that their investigation has led to the choreographer, Sasha, because she thinks he can do whatever he wants because he's the boss.

SVU learns that the male dancers make out with the women and film them and then Sasha threatens to make the video public if they don't have sex. No one will testify, however, until Kat finds Rose, an ex-ballerina who quit before her first dance. Rose says she went to Alistair, the company manager, for help and he blackmailed her into participating in an auction where she would be expected to have sex with the winner.

Carisi says it's not enough to prosecute, so Benson sets up an undercover operation, but Rollins is disappointed to find out that the operation includes arresting the victim for prostitution.
