On this week's Person of Interest…
The Machine comes up with a number for a man named Judge Gates.
A Russians crime gang kidnap the Judge's son and hold him ransom. They don't want money, but rather a woman who stands trial on Gates' watch to go free. She helps them launder their dirty money.
The Judge prevents her from being sentenced in order to rescue his son.
Reese kidnaps the woman in order to prevent the Russians from killing the Judge and his son.
In the end, Reese saves the Judge and his son, allows a few of the Russian members to be captured by the police, and even gains a little trust from Finch.
Meanwhile, Detective Carter and Fusco begin to work together.
