“I am not imagining this,” Lo Blacklock (Keira Knightley) insists in the trailer for The Woman in Cabin 10

A journalist assigned to cover the story of a luxury superyacht’s first voyage, Lo has just seen a woman fall to her death — but no one believes her. Not Richard Bullmer (Guy Pearce), the superyacht’s wealthy owner, nor her fellow passengers, played by the likes of Kaya Scodelario and Daniel Ings. Nevertheless, as you can see in the trailer above for this adaptation of Ruth Ware’s bestselling novel of the same name, Lo refuses to back down. She’s determined to uncover what happened to this mysterious woman even at the risk of her own life. What was supposed to be a cushy assignment for work turns into a twisty and thrilling excursion on the high seas. 

Even though Lo is surrounded by naysayers on the boat, writer and director Simon Stone is adamant that there’s no ambiguity here: Something on this yacht isn’t quite right. “You never question whether or not she saw what she saw,” Stone tells Netflix. “You agree completely with her. It’s her struggle against the conspiracy.”

You can get a glimpse at a few of the yacht’s other guests in the trailer. In addition to Pearce’s Bullmer, there’s gossipy Heidi (Hannah Waddingham), influencer Grace (Scodelario), media fortune heir Adam (Ings), and Lo’s photographer ally Ben (David Ajala), to name a few. “It’s an incredibly stacked cast,” Stone says. “Keira has led in an extraordinary way, and Guy as well. But the entire ensemble has been amazing.”

As touchpoints for the film, Stone looked at classic ’70s thrillers like Marathon ManKlute, The Conversation, and Three Days of the Condor. He also cites the work of Alfred Hitchcock — the Master of Suspense’s film The Lady Vanishes shares a great deal of DNA with Ware’s original novel. “Finding that tradition, but with a different gender and a different energy, has been really exciting,” Stone adds.

The Woman in Cabin 10 stars Knightley, Pearce, Ajala, Art Malik, Gugu Mbatha-Raw, Scodelario, David Morrissey, Ings, Waddingham, Gitte Witt, Christopher Rygh, Pippa-Bennett-Warner, John MacMillan, Paul Kaye, Amanda Collin, and Lisa Loven Kongsli.

Will Lo uncover the answers she’s looking for and make it back to shore alive? You’ll have to watch The Woman in Cabin 10 when it sails onto Netflix on Oct. 10.
