‘Based on a True Story’ Season 2 Trailer: Kaley Cuoco and Chris Messina Search for a Serial Killer at a Sex Club

The comedy thriller co-stars Tom Bateman, Liana Liberato, and Melissa Fumero.

Kaley Cuoco and Chris Messina are back solving crime, but just how many serial killers live in the suburbs?

“Based on a True Story” Season 2 centers on new parents Ava (Cuoco) and Nathan (Messina) who try to tame their true crime obsession amid the arrival of their baby. But after discovering that their friend Matt (Tom Bateman) was the Westside Ripper in Season 1, the duo agree to keep his secret if he stops killing people and anonymously shares his story on their true crime podcast. So who is behind the new copycat Westside Ripper killings?

The official synopsis reads: “Focused on taking care of her family, Ava (Cuoco) is determined to resist her true crime obsession and return to work as a real estate agent while Nathan trains private tennis clients. But a series of new murders pulls her back in – is Matt (Bateman) behind the slayings? Is Tory (Liana Liberato), now entangled in a relationship with Matt, in danger? For a while, life is good: Ava’s TikTok habit and her new friend Drew (Melissa Fumero) provide a welcome distraction, and Nathan’s (Messina) all in on reigniting his tennis career as well as his friendship with Matt — until danger comes knocking, literally.”

The comedy thriller will debut Season 2 with all eight episodes.

Cuoco and Messina both serve as executive producers on Season 2, along with series creator Craig Rosenberg, Jaclyn Moore, Alex Buono, and Aggregate Films’ Jason Bateman and Michael Costigan.

The IndieWire review pointed to how the first season had a “finale so jarring that it clearly assumes a second season,” adding, “Ava and Nathan’s marital and financial hardship gets minimal screen time where they actually work through it, and one finale reveal is so completely unearned and unexpected that it almost doesn’t register.”

The review continues, “‘Based on a True Story’ devolves into the most predictable possible outcome, where crime begets crime and chaos yields chaos, but with none of the elegance and innovation of a tightly-wound time bomb like ‘Barry.’ This is a series that unravels quickly, and that’s assuming that it was ever raveled (so to speak) in the first place.”

“Based on a True Story” Season 2 premieres November 21 on Peacock. Check out the trailer below.
