The series is adapted from Alafair Burke's 2019 novel The Better Sister; Burke is a former prosecutor turned bestselling crime writer, and her legal-world experience informs the story's procedural spine and its interest in how the truth gets constructed.
Jessica Biel and Elizabeth Banks not only star as the estranged sisters but also serve as executive producers, marking the first time the two actresses headlined a project together and steering the adaptation from behind the scenes.
Despite a divided critical response, the show became an immediate hit for Prime Video, rocketing up the platform's most-watched rankings in the weeks after its premiere on the strength of its two-star billing and page-turner plotting.
The Better Sister is a twisty Prime Video limited series adapted from Alafair Burke's 2019 domestic-noir novel, headlined by Jessica Biel and Elizabeth Banks, who also executive produce. Built around the fraught, competitive bond between two sisters, the series trades in the glossy, secret-riddled suspense that has made the modern domestic thriller a streaming staple, using a shocking murder to pry open a family's carefully maintained facade.
Biel plays Chloe, a polished, successful media executive with an enviable life, while Banks plays her estranged, harder-luck sister Nicky. The two are violently thrown back together when Chloe's husband — who happens to be Nicky's ex — is murdered, and the investigation drags long-buried secrets, old resentments, and competing versions of the truth into the light. Corey Stoll and Kim Dickens co-star in a story that keeps shifting the ground beneath the audience's assumptions about who these women really are.
While reviews were mixed on the show's later-episode twists, the pairing of Biel and Banks proved a genuine draw, and the series quickly climbed into Prime Video's most-watched charts after its release. A sleek, bingeable mystery powered by two committed lead performances, The Better Sister is streaming on Prime Video.
