When an FBI agent who was working undercover is found brutally murdered in the bathroom of a petrol station, the CSI team are called in to help the victim's partners find the killer. However, the more the case proceeds, it becomes increasingly apparent that all is not what it seems and that the agents are hiding something.
Tropes:
- Bittersweet Ending: With Miles' help, the Las Vegas Police Department is able to arrest Os Punhos, rescue the underage girls being held prisoners, and shut down the prostitution ring. But Miles' friends are dead and he faces an uncertain future. Nevertheless, the episode ends on a hopeful note with Ray visiting Miles in psychiatric care and giving him a copy of Don Quixote to help pass the time.Miles: [wistfully] "As I recall... Quixote regained his sanity in the end. But his melancholia persisted. He died emotionally broken and alone."Ray: "Well, they didn't have antidepressants back in those days."[Miles and Ray share a smile at the irony]
- Heroic BSoD: When Ray and Brass find Miles, he has become catatonic and depressed after the deaths of his friends Billy Ray and Emma.
- The Reveal: Agents Beckman, Stanley, and Hatford are actually psychiatric patients posing as FBI agents.
- Wham Line: Wendy sends Agent Hatford's DNA to the FBI office in Quantico for identification. However, when she receives an e-mail reply from the FBI...Wendy: "I just got this e-mail from FBI Quantico, and there is no record of any agent by the name of William Ray Hatford. They're saying this guy was a fake."
Miles: [reading Don Quixote] "Chapter One. At a village of La Mancha, whose name I do not wish to rember, there lived a little while ago, one of those gentlemen who are wont to keep a lance in the rack, an old buckler, a lean horse and a swift greyhound."
Ray: [smiling] "Those windmills you tilted at, they really were giants."
