Nerdy teenager Zach is getting dirty pics and suggestive texts from his English teacher, but vanishes on his way to a secret tryst with her. Benson and Dodds learn Miss Barnap has been giving lessons in lust to some students, but the photos to Zach were actually sent by the school's wrestling coach. The squad later finds the kidnapped boy in the man's remote cabin.  Zach's parents won't let him testify, so Olivia and Mike ask some of the coach's past victims to come forward. But one has a better idea...he gets a videotaped confession from the coach by torturing him to death. Also, Rollins apparently survived childbirth.In our 200th episode, we're talking about Special Victims Unit season 17 episode 10* "Catfishing Teacher."
