Ep 18. Yesterday

Detectives Robert Goren (Vincent D'Onofrio) and Alexandra Eames (Kathryn Erbe) investigate a homicide case that leads them to uncover a dark past involving the victim and the suspect. The victim, a young woman named Kate, was found dead in her apartment with evidence pointing to her ex-boyfriend, a wealthy businessman named Bobby Masconi (played by guest star Paul Adelstein).

As Goren and Eames dig deeper into the case, they discover a complicated web of secrets and lies. Kate had a troubled past, having grown up in foster care and struggled with drug addiction. Masconi played a role in her dark history, having financed her drug habit and even physically abused her in the past. However, the detectives soon realize that Masconi is not the only suspect.

The investigation takes a turn when the detectives find evidence linking Kate to a man named Eddie, who was also involved in the drug scene. Eddie is revealed to be the biological father of Kate's son, and both he and Masconi had been vying for custody of the child. As Goren and Eames dive deeper into their history, they discover Eddie's violent past and his connection to a string of suspicious deaths.

Meanwhile, Goren deals with his own personal demons as memories of his father's murder resurface. Goren's father was a corrupt police officer who was killed in the line of duty, and Goren was left with a sense of guilt for not speaking out against his father's corrupt actions. As Goren struggles with these memories, he finds himself becoming more obsessed with the case and more determined to solve it.

The episode culminates in a dramatic confrontation between Goren and Masconi, where Goren uses his knowledge of Masconi's past to bring him to justice. The episode ends with Goren struggling to come to terms with his own past and the legacy of corruption in the criminal justice system.

Overall, "Yesterday" is a compelling and complex episode that explores the themes of abuse, addiction, and corruption. The episode is notable for its strong performances by the guest stars and for its nuanced portrayal of Goren's character. Fans of Law & Order: CI will not be disappointed by this gripping and emotionally resonant episode.
