The Woman in Cabin 10 is about murder, but not only in the traditional sense. Beneath the act itself lies another form of violence: the manipulation of perception, the control of truth, and the privilege that shields the guilty.
Simon Stone’s adaptation of Ruth Ware’s novel transforms The Woman in Cabin 10 from a confined mystery into a study of power. It questions who defines what is real, and how easily the truth bends when those in control decide what should be seen.

The architecture of gaslighting
Keira Knightley’s Lo Blacklock moves through a world built to silence her. The yacht is polished, the guests refined, the champagne endless, but everything around her exists to deny what she knows she saw.
What begins as paranoia becomes proof that influence can twist perception until truth looks like delusion. Each attempt to speak is met with a smile, a correction, or a reminder that she should relax.
Gaslighting shapes every frame of The Woman in Cabin 10. Control doesn’t always need force. Sometimes it hides in wealth, civility, and the soft insistence that she must be mistaken.
Privilege as power
Simon Stone builds his mystery like a reflection that refuses to stay still. The deeper Lo looks, the less certain she becomes of what’s real. That tension between clarity and distortion is where the film finds its pulse.
The people surrounding Lo live in a world where truth bends to privilege. Their power doesn’t just protect them; it rewrites the story. On that yacht, accountability is selective, and morality is an accessory to appearance.

The performance that carries the weight
Knightley gives Lo a sharp vulnerability that defines the film. Every gesture and every silence feel calculated, watched, and doubted. She isn’t a detective chasing a killer but a witness struggling to exist in her own account of events.
Her restraint turns into strength, her fear into persistence. As The Woman in Cabin 10 unfolds, her silence becomes the loudest act of defiance.

Seeing through the illusion
The Woman in Cabin 10 treats luxury as camouflage. Every surface gleams, every exchange hides intent, and every secret is dressed in elegance. The yacht’s beauty conceals decay, and the calm waters surrounding it reflect the danger within.
Stone’s direction gives the story of The Woman in Cabin 10 a cold precision that mirrors the characters’ emotional distance. What looks controlled begins to fracture, revealing a world built on denial and manipulation.

The Woman in Cabin 10 and the cost of being heard
By the end, Lo’s survival feels raw and deliberate. The film doesn’t celebrate her victory; it observes it. The Woman in Cabin 10 understands that being believed isn’t justice, only the beginning of it.
Her truth surfaces, but not without consequence. She walks away changed, aware that truth alone can’t protect anyone from disbelief.
Rating with a touch of flair: 5 out of 5 masks sinking beneath calm waters, refusing to stay buried.
