A trailer has just released for Netflix’s adaptation of The Woman in Cabin 10, a book by Ruth Ware. Staring Keira Knightley, The Woman in Cabin 10 promises to be a suspenseful mystery and thriller.

As indicated by the trailer, the film follows a journalist, played by Knightley, who finds herself onboard a luxury yacht for a travel assignment. Things soon turn dark when she hears a struggle, only to look out over her balcony and see a body floating in the water.

The trailer continues and we discover that everyone aboard the yacht is accounted for. Knightley’s character insists on what she has seen, but no one believes her. She then begins to cross paths with danger and suspects that someone is attempting to “silence” her.

It will be exciting to see this mystery unfold. Did Knightley’s character see what she claims to have seen, or is it paranoia? Is she really in danger, despite what all the other characters say?

You can find out by watching The Woman in Cabin 10 when it releases on Netflix on October 10th.
