Keira Knightley Unravels a Murder Mystery at Sea in Twisty The Woman in Cabin 10 Trailer

Keira Knightley is delving into a murder mystery on the high seas.

On Tuesday, Aug. 26, Netflix debuted the trailer for The Woman in Cabin 10, which stars Knightley, 40, as Laura “Lo” Blacklock, a journalist who witnesses a possible murder while on a luxury cruise.

“While on board a luxury yacht for a travel assignment, a journalist witnesses a passenger thrown overboard late at night, only to be told that it didn’t happen, as all passengers and crew are accounted for,” the synopsis teases. “Despite no one believing her, she continues to look for answers, putting her own life in danger.”

Directed by Simon Stone, the movie is adapted from the 2016 novel by Ruth Ware. The movie also stars Guy Pearce, David Ajala, Hannah Waddingham, Art Malik, Gugu Mbatha-Raw, Kaya Scodelario, David Morrissey and Daniel Ings.

Director Stone told PEOPLE in July that Knightley has “done an extraordinary job of having this incredibly charismatic core that you totally believe, because it’s a gaslighting story.”

“Historically, there’s this tendency of treating female psychology as something that’s not to be trusted. And I went, no, I want the performance to be so convincing that you just go, ‘I believe you. I’m on your side, and I just want, with you, to find out what happened.’ And [Keira]’s so good at that.”

Author Ware, who published a sequel book titled The Woman in Suite 11 in July, said in a statement that the movie “is about a woman who experiences something wrong, reports it truthfully, and isn’t taken seriously because of who she is.” 

“Too many people know what that feels like and I think we want vindication for ourselves as much as Lo,” Ware said.

The Woman in Cabin 10 is on Netflix Oct. 10.
