The Woman in Cabin 10 is on Netflix and the film stars Keira Knightley as Laura "Lo" Blacklock, a journalist covering the maiden voyage of a luxury cruise ship.
Not long into her stay, she is convinced she has witnessed a passenger being thrown off the balcony in cabin 10, but she is informed no-one was staying in said cabin.
The final episode saw Lo trying to escape the clutches of Richard Bullmer (Guy Pearce) and his staff, some of whom were in on his dark secret.
After Lo finally caught up with the mystery woman, she believed it to be Anne (Gitte Witt), Richard's dying wife.
However, after noticing some subtle differences in the woman's behaviour, Lo realised it was not Anne after all. READ MORE : 'Chilling' Netflix documentary from 'master
