There are family histories that seem finished until something forces them to go back into the past. In The Better Sister (The Better Sister), an unexpected murder brings two sisters who have been estranged for years back into each other’s lives, forcing them to confront secrets they believed were forgotten.
Starring Jessica Biel and Elizabeth Banks, the miniseries blends thriller, mystery, and family drama in a story that begins with a crime but quickly widens its questions. Because to understand what happened, you must also look back, at the relationship between these two women and everything that remained unresolved.

Available on Prime Video, The Better Sister has eight episodes, a perfect length for a weekend marathon.
Jessica Biel and Elizabeth Banks portray two very different sisters
Jessica Biel steps into the shoes of Chloe, a woman who built a successful and seemingly steady life. Elizabeth Banks portrays Nicky, her sister, with whom she maintains a relationship marked by distance and differences.

The death of Adam, Chloe’s husband, completely changes that dynamic. The investigation brings Nicky back into the picture and, with her, questions about the sisters’ past also return.
A murder that opens up too many questions
The series is based on the novel The Better Sister, by Alafair Burke, and builds the mystery from multiple layers of the family history.

As the investigation progresses, new clues appear and the view of the characters shifts. The question isn’t only who is behind the crime, but also what actually happened between the sisters and how much of what they recount aligns with the truth.
Eight episodes to watch straight through
The miniseries consists of eight episodes of about an hour each. Its structure combines the murder investigation with flashbacks that allow reconstructing the story of Chloe and Nicky.

That exact combination is what sustains the intrigue: while the present tries to uncover answers, the past adds new pieces to a family bond that is far more complex than it seemed.
Why add The Better Sister to your list?
