The Better Sister is a gripping American limited thriller series starring Jessica Biel and Elizabeth Banks, based on Alafair Burke’s 2019 novel. Adapted by Olivia Milch, with Burke consulting, the show premiered on May 29, 2025. Directed and executive produced by Craig Gillespie, it is a joint effort from Tomorrow Studios and Amazon MGM Studios.

The Better Sister unravels the tense reunion of two estranged siblings, Chloe (Jessica Biel) and Nicky (Elizabeth Banks), after Chloe’s husband—and Nicky’s ex—Adam (Corey Stoll)—is slaughtered. Critics say there is a lot going on in the series, and trying to cram it all into eight episodes created a total mess.

Meanwhile, Netflix fans buzz over A Widow’s Game, wondering if it is based on a true story.

Beneath every twisted lie and hidden motive in A Widow’s Game lies a chilling question—how much of this dark story is ripped straight from reality, and what secrets remain buried?

When horror hits home: Is A Widow’s Game based on real life?

Netflix’s A Widow’s Game pulls from a chilling real-life nightmare—the infamous 2017 Black Widow case in Valencia, Spain. Antonio Navarro Cerdán, a 36-year-old engineer, was brutally ambushed and fatally sliced in his apartment garage by a hidden assailant lurking among the cars. The police quickly realized this was no random crime—nothing was stolen, and every detail screamed cold, calculated slaughter. This sinister true story fuels the film’s dark, gripping atmosphere.

A Widow’s Game is a 2025 Spanish crime drama directed by Carlos Sedes, inspired by the infamous Patraix case. Featuring Ivana Baquero, Tristán Ulloa, and Carmen Machi, the film premiered on Netflix on May 30, 2025. While Netflix offers this gripping true-crime drama alongside a treasure trove of thrillers for fans, The Better Sister remains exclusive to Amazon Prime—for now, at least.
