An Agatha Christie-style mystery on a luxury yacht, The Woman in Cabin 10 sees Keira Knightley trying to get to the bottom of a murder at sea.

The twist? Even though she's convinced she saw a body in the water after hearing an argument in the next door cabin, everybody else on the boat seems to be convinced that there was nobody in the next cabin.

Guy Pearce, David Ajala, Art Malik, Gugu Mbatha-Raw, Kaya Scodelario, David Morrissey, Daniel Ings, and Hannah Waddingham make up the all-star cast of Simon Stone's adaptation of the bestselling 2016 novel by Ruth Ware.

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