Keira Knightley leads the cast of the new Netflix thriller as a journalist who is convinced something is amiss. The film, based on Ruth Ware's novel, arrived on the streamer on Friday (10th October) and has shot to the top of the Netflix Top 10 list despite a relatively poor critical reception.
Knightley plays investigative journalist Lo, who is convinced she sees a passenger thrown overboard the luxury yacht she is travelling on – even though everyone aboard claims that nothing is amiss and all passengers and crew are accounted for. As her paranoia grows, it becomes apparent that she was right all along.
After discovering that the woman she saw in the supposedly unoccupied cabin 10 is the spitting image of Anne (Lisa Loven Kongsli), things start to click into place. Richard (Guy Pearce) had invited a doppelgänger, Carrie (Gitte Witt), to the maiden voyage to temporarily switch places with his wife, Anne, so he could change Anne's will to leave everything to him. However, when Anne discovered Carrie and Richard scheming in cabin 10, a fight broke out, and she fatally hit her head before Richard pushed her overboard. Carrie then became Anne for the rest of the trip.
Carrie confides this to Lo when she traps her in a storage room. Lo is missing for several days, which Dr Robert Mehta (Art Malik) and Richard cover up as illness. When everyone leaves the ship, Lo escapes, finds a hidden key, and steals Anne's confession. As she descends, Robert blocks her way with a syringe. Lo fights him off, but Ben (David Ajala) appears and fights Robert. In the altercation, Robert accidentally injects Ben with the lethal syringe, and Ben dies.
Lo leaps off her balcony into the icy waters and swims to shore. Robert tells Richard that Lo could not have survived. Richard takes Carrie to rewrite Anne's will. During the gala preparations, Lo gatecrashes and reveals the truth about the doppelgänger to a crew member, proving it by letting her read the confession.
