The Better Sister is a 2025 American drama-thriller series directed by Olivia Milch, starring Jessica Biel and Elizabeth Banks as two estranged sisters whose fragile lives are torn apart when a murder forces buried secrets into the open. Dark, propulsive, and rooted in family psychology, it arrives on K-Time with a full Persian dub.

What is The Better Sister about?

Chloe has built what looks like a stable life — a devoted husband named Adam, a teenage son, and a comfortable home. Her sister Nicky, by contrast, is still fighting her way through addiction, drifting at the edges of the family. When Adam is killed, the neat boundary between the two women's worlds collapses. Detectives and grief collide, but so do old resentments, long-buried choices, and questions about who in this family actually knew whom. Each episode peels back another layer of a shared past that neither sister has been fully honest about — with the other, or with herself.

Cast & crew

Jessica Biel plays Chloe, the outwardly composed sister holding the family together, bringing her knack for tight dramatic restraint to the role. Elizabeth Banks takes on the chaotic, searching Nicky with characteristic precision. Corey Stoll, Kim Dickens, and Gloria Reuben round out a strong supporting ensemble, while Bobby Naderi — an Iranian-American actor — appears in a notable recurring part.

Context & significance

Psychological suspense centered on two sisters whose bond has fractured over years of grief, resentment, and different life paths is a genre that resonates strongly with diaspora audiences. Persian-speaking viewers who grew up navigating the tension between family loyalty and personal survival will find familiar emotional territory here. The show belongs to the tradition of slow-burn domestic thrillers that prioritize character depth over spectacle. It is available on K-Time with a Persian dub, meaning you can watch an English-language production entirely in Farsi without subtitles — a rare and convenient option for viewers at different levels of English comfort in the household.
