MURDER at sea!

Keira Knightley sets sail on a luxury superyacht for a chilling killer thriller...

- 

An all-expenses-paid assignment on a luxury superyacht sounds like the perfect respite for hardworking investigative journalist Lo Blacklock (Keira Knightley) in this high-tension thriller. But that's until she witnesses a murder on board and finds herself at the mercy of the killer, who wants her silenced!

'You meet Lo after she's been traumatised while working on a story. Somebody she should have been protecting dies,' says Keira, 40. 'She thinks that this cruise job will be easy, but it turns into this very dramatic tale!'
