Introduction

Based on Ruth Ware’s 2016 thriller novel, The Woman in Cabin 10 unfolds as a claustrophobic mystery at sea. It stars Keira Knightley as Lo Blacklock, a travel journalist, who boards a luxury cruise and thinks she witnesses a murder — but no one believes her. The tension, the setting, and the unraveling puzzles position it as one of 2025’s notable mystery thrillers.

Story Outline & Highlights

Lo Blacklock is jaded and burnt out. She’s covering a once-in-a-lifetime cruise for a terminally ill philanthropist and her husband. On the first night, Lo hears a scream and glimpses what appears to be a woman thrown overboard. But when she checks, no one is missing and no one saw it. Thus begins her spiral into distrust, paranoia, and danger. 

As she digs deeper, she uncovers deception, identity swaps, and hidden motives. Twists and half-truths mark almost every turn. In the ending, the truth about the “Anne” on board — or rather, the impersonator “Carrie” — comes to light.

Performances & Execution

• Keira Knightley (Lo Blacklock) brings emotional vulnerability to a role that requires both skepticism and courage. Critics agree her performance is a key anchor that makes us care.

• Supporting Cast: Guy Pearce and Gugu Mbatha-Raw add weight to a cast that occasionally feels understaffed in their motivations. 

• Cinematography & Atmosphere: The film is beautifully shot — the cruise ship, the sea at night, the corridors and decks all contribute to an unsettling isolation and claustrophobia. 

• Pacing & Tension: Many reviews note that the first half has promise, but the suspense ebbs in the middle. The final act tries to regain momentum.
