Laura “Lo” Blacklock is a travel journalist invited on the maiden voyage of a luxury superyacht. She expects a relaxing trip filled with beautiful views and fine dining. But one night, she sees something shocking — a woman falling into the sea. By morning, everyone is still on board, and no one believes her. Stuck far from shore, Lo must find the truth before it’s too late.
The film is directed by Simon Stone and based on the bestselling novel by Ruth Ware. Keira Knightley stars as Lo, joined by Guy Pearce, David Ajala, Art Malik, Gugu Mbatha-Raw, Kaya Scodelario, David Morrissey, Daniel Ings, and Hannah Waddingham. Filming took place on the Isle of Portland in Dorset, England, and aboard the stunning superyacht Savannah, giving the movie both a glamorous and tense atmosphere.
Netflix has released first‑look images and a teaser trailer, showing glimpses of the film’s suspense and luxury setting. Keira Knightley has said she was drawn to the role for its psychological depth, while author Ruth Ware has praised the adaptation and the cast. The Woman in Cabin 10 will be released on October 10, 2025, and is expected to be one of the year’s most talked‑about thrillers.
