🔥 Premise: Sisters. Secrets. Suspicions.

On the surface, Chloe (Jessica Biel) has it all — a prestigious media career, a sleek Manhattan lifestyle, a charming husband (Corey Stoll), and a bright teenage son (Maxwell Acee Donovan). Her estranged sister Nicky (Elizabeth Banks), on the other hand, has spent years battling addiction and scraping by. The two women haven’t spoken in years.

That changes in a heartbeat.

When Chloe’s husband Adam is found murdered in their upscale apartment, long-buried tensions resurface. As suspicion falls on someone shockingly close to home, Chloe and Nicky are forced into an uneasy alliance to protect the people they love — and to uncover the truth.

But the more they dig, the more they realize the lies didn’t start with the murder. The real mystery lies within their shared past — and it may not be over yet.

⭐ Cast & Characters

• Jessica Biel as Chloe – Ambitious, controlled, and fiercely protective, Chloe has worked hard to outrun her past. But her present may be more fragile than she thinks.

• Elizabeth Banks as Nicky – Once written off as the family disappointment, Nicky returns with more insight — and secrets — than anyone expects.

• Corey Stoll as Adam – Chloe’s seemingly perfect husband, whose hidden past is only revealed after his death.

• Maxwell Acee Donovan as Ethan – The teenage son caught between two mothers and a family unraveling.

• Kim Dickens, Gabriel Sloyer, and Bobby Naderi round out the supporting cast as key figures in the murder investigation.

🎬 Behind the Scenes

With Craig Gillespie (Cruella, Pam & Tommy) at the helm, and showrunners Olivia Milch and Regina Corrado steering the narrative, The Better Sister promises a stylish, psychological dive into familial trauma. Executive producers include both Biel and Banks, who also bring their creative fingerprints to the tone and tension of the series.

🧠 Themes & Tone

This isn’t just a whodunit — it’s a why-did-they. The series blends courtroom suspense, emotional drama, and the kind of razor-sharp character study you’d expect from prestige thrillers like Big Little Lies or Sharp Objects. It tackles:

• Family loyalty vs. betrayal

• The long reach of childhood trauma

• Public perception vs. private reality

• Sisterhood — fractured and forged anew

🎯 Why You Should Watch

• Jessica Biel & Elizabeth Banks — two powerhouse performers sharing the screen in roles that demand emotional depth and razor-edge intensity.

• Unpredictable twists — With every episode, new revelations reshape what you think you know.

• Gritty yet elegant — Set against a sleek urban backdrop, the show explores how privilege can mask dysfunction — until it can’t.

💬 Final Word

The Better Sister is more than a murder mystery — it’s an exploration of the stories we tell ourselves, the roles we play, and the people we hurt to survive. If you're into twisty, character-rich dramas with high emotional stakes, don’t miss this one.

📆 Mark your calendars — The Better Sister premieres May 29 only on Prime Video.
