Law and Order: SVU's new episode entitled 'Decaying Morality' will be the biggest shocker of this season.

'Law and Order: SVU': All Hell Breaks Loose In New Episode

Detective Benson (Mariska Hargitay) and Detective Rollins (Kelli Giddish) find a teenaged girl crying in the street, with her clothes torn.

Jenna Davis says she was raped in a pizzeria bathroom by Jerome Jones. Jones has a criminal record as well as a pending lawsuit against the NYPD.

Amaro's Father Returns & Things Take Sharp Turn on New 'SVU'

Because there's very little evidence to charge Jones, the SVU detectives released him until an arrest can be made.

Angry that his daughter's alleged rapist wasn't arrested, Jenna's father takes matters into his own hands and things take a turn for the worst.

Based on the new sneak peek, which can be seen below, Jenna's father kills Jones and their lives have officially changed forever.

The man says he was simply trying to get a confession and he didn't mean to kill the man, and sadly, he's arrested and now on trial for murder.

The biggest twist of the season comes, when Jenna's father asks her if he was really the man who raped her and her response isn't quite what detectives are expecting to hear.

In the video, Jenna is talking to her father while he is in jail, and when he asks her about the accident she responds, "Even I'm not sure it's better for you if I just say it was."

Could Jenna's alleged rapist actually be an innocent man after all? Fans will have to tune in to find out.

Law and Order: SVU airs every Wednesday night at 9 p.m. on NBC.
