Dateline NBC “Devil’s Bargain” August 29 2025 Recap & Preview

Dateline NBC returns with a gripping two-hour episode titled Devil’s Bargain on Friday, August 29, 2025, at 9/8c. Andrea Canning reports on the heartbreaking case of Kelsey Berreth, a young mother whose disappearance shocked the nation—and whose murder was ultimately solved through a dark deal with an unlikely witness.

In late 2018, Kelsey Berreth vanished without a trace after being seen at a Colorado grocery store with her infant daughter. As the days passed and she failed to respond to calls or texts, concern grew into panic. Berreth’s fiancé, Patrick Frazee, became a person of interest—but there were no immediate signs of foul play, and her body was never found.

The investigation took a dramatic turn when Krystal Lee, a nurse from Idaho and secret girlfriend of Frazee, came forward with disturbing revelations. Her cooperation with law enforcement became the linchpin in unraveling a carefully orchestrated and deeply disturbing plot. Lee admitted to cleaning up the crime scene and later agreed to testify against Frazee in exchange for a plea deal—hence the episode’s title, Devil’s Bargain.

In this episode, Dateline features emotional interviews with Kelsey’s family members and detailed accounts from the lead investigators who worked the case. Viewers will hear how law enforcement pieced together a timeline using surveillance footage, phone records, and Krystal Lee’s testimony—ultimately leading to Frazee’s arrest and conviction.

The episode also explores the emotional and legal aftermath of the case, the trial that captivated national audiences, and the justice Kelsey’s family fought so hard to achieve.
