The police's Critical Response Team is brought in to investigate Lloyd Zuker's death. Theo lies about seeing Zuker with a gun to help Joe but his story doesn't hold up under scrutiny and lead investigator Frank Conti tries to get him to turn on Joe, threatening to charge Joe with murder and Theo with the attempt to pervert the course of justice.

Meanwhile, the detectives investigate the murder of a man whose body is pulled from a lake. Nicole comes out of surgery.
