‘Based on a True Story’: A New Killer Is on the Loose in Season 2 Trailer (VIDEO)

Peacock‘s outrageous serial killer comedy Based on a True Story is almost back with Season 2 as the streamer unveils the official trailer, poster, and photos for the upcoming chapter.

Starring Kaley Cuoco, Chris Messina, Tom Bateman, Liana Liberato, and the latest addition, Brooklyn Nine-Nine‘s Melissa Fumero, Based on a True Story is officially set to premiere with eight all-new episodes on Thursday, November 21. As fans will recall, the series finds Ava (Cuoco) and Nathan Bartlett (Messina) become entwined with serial killer Matt (Bateman) when they convince him to create a true crime podcast with them. Things become complicated when Ava’s sister Tory (Liberato) gets in the mix as she shows a liking to Matt.

In Season 2, Ava and Nathan are three months into being new parents and are focused on caring for their family, with Ava putting aside her true crime obsession by returning to work as a real estate agent and Nathan taking on private tennis clients. But just as they’re getting their lives back on track, a string of new murders pulls Ava back in as she tries to uncover if serial killer Matt is behind them. She’s especially invested considering her sister Troy’s ties to Matt.

But for a while things are good though as Ava makes a new friend in Drew (Fumero), providing her with a distraction as Nathan is eager to reignite his tennis career as well as his friendship with Matt. The good times can’t last forever though as danger comes knocking at their doors. In addition to the premiere date, and images, below, Peacock unveiled a fun teaser, which you can watch, above.

Series showrunner, executive producer, and writer Annie Weisman noted in a statement, “I first discovered Based on a True Story as a fan of Kaley Cuoco and Chris Messina, and I instantly loved the show’s addictive blend of dark humor, pulpy action, and relatable characters. In Season 2, we’ve built on those exciting themes while introducing propulsive new character dynamics and a forward-moving murder mystery.”

Weisman complimented the cast as she added, “Kaley and Chris deliver exceptional performances, bringing depth, authenticity, and comedic chemistry to every moment. Tom Bateman’s portrayal of Matt effortlessly shifts between charming and chilling, while Liana Liberato embodies Tory’s feisty free spirit. And we’re thrilled to welcome Melissa Fumero to the series in a surprising new role. The entire cast excels at balancing humor and heart, creating a deeply funny, unpredictable, and resonant viewing experience. I can’t wait for you to join us on this wild ride.”
