Jacob Lowenstein, recently released after serving a jail sentence for his daughter's murder (per the Season 1 episode "[[{{Recap/LawAndOrderS1E9Indifference}} Indifference]]"), is severely wounded in a hit and run. Lowenstein shows no remorse for his crimes, denies all responsibility, and has already broken the terms of his parole by moving in with his fiancee Cheryl and her children. The detectives are led to Joyce Draper, Lowenstein's therapist as part of an experimental treatment program he undertook in jail. She has no alibi, and DNA on her car is matched to Lowenstein. Van Buren and Southerlyn discover that Lowenstein had taunted Draper during the therapy sessions, threatening to re-offend as soon as he was released. She had checked up on Cheryl's family and learned that Cheryl's daughter broke her arm in an "accident" right after Lowenstein moved in. The detectives arrest Draper for the murder of Lowenstein, who has now died.

At trial, the jury is shown tapes of Lowenstein's therapy sessions with Draper, in which he all but openly threatened to harm Cheryl's children. She denies killing Lowenstein, but can't explain why she didn't try to speak to Cheryl herself or go to the police. The defense tries to argue that, since Draper's car was kept in a public place, anyone else could have had access to it and killed Lowenstein. [=McCoy=] says that while Draper is a sympathetic defendant, this is no excuse for taking the law into her own hands when she could have stopped Lowenstein legally. The jury acquits and the [=DAs=] reflect that this was reasonable behavior.

* BrokenBird: Jacob's ex-wife Carla, who is still living in terror of him.
* ContinuitySnarl: Played with. When discussing the case, the prosecutors say Lowenstein got a lenient plea deal because it wasn't a slam dunk case. Although ''[[{{Recap/LawAndOrderS1E9Indifference}} Indifference]]'' ended with a jury conviction, it's entirely possible that the appeals court got involved and vacated the verdict, while tossing some evidence out, leading to the plea deal.
