No, Based on a True Story isn’t a true story. It’s the comical antics of a young suburban couple who made an insane decision to make ends meet. Ava and Nathan Bartlett, played by Kaley Cuoco and Chris Messina, are facing financial difficulties while expecting their first child. With an abundance of naive enthusiasm, Ava convinces Nathan that a true crime podcast is the solution to all of their problems. Then the fun begins!

A ruthless serial killer, the Westside Ripper, is terrorizing their city. Ava is thrilled, and her deep fascination with true crime stories causes her to run toward the danger instead of away from it. So, she and Nathan begin an adventure to reveal the killer and revive their failing marriage, all while creating a fan base for their brand-new podcast.

Based On a True Story

Ava is a young wife, realtor, and soon-to-be mom with a growing obsession with true crime. She belongs to an equally true crime-obsessed book club who do nothing to asway her ridiculous notion of pursuing the killer. Her husband, Nathan, loses his job, plunging both into a sense of dire desperation. So, when Ava comes to believe that the solution to their problems is a true crime podcast – with the killer, Nathan is eventually convinced. 

The official synopsis for this dark comedy is that a “realtor, a former tennis star, and a plumber” take the opportunity to capitalize on America’s obsession with true crime. Who’s the plumber, you ask? That’s one of the many questions you’ll get answered when you begin watching Based on a True Story.  


Peacock released a trailer on May 15, 2023. The trailer shows us that Nathan is a less-than-willing partner in these true-crime antics. But Ava, his wife, has enough eagerness for both of them. The couple’s marriage is in a rut, and Ava compensates for the lack of excitement in her marriage by developing an ever-growing true crime fandom. 

Despite enjoying her true-crime book club, Ava recognizes that it isn’t enough. She and Nathan still face serious problems that need a solution. 

On one fateful day, the couple witnesses the murder of an associate by the local serial killer, dubbed the Westside Ripper. Instead of the logical response of fear of this killer of women, Ava decides that the story of this mystery needs to be told. She even suggests that she and Nathan invite the killer to be a guest on their podcast!

The couple’s inexperience, lack of decorum, and general clumsiness lead to chaotic and hilarious situations – one after the other.
