Kiera Knightley plays a political journalist who takes on what she expects to be a lighter assignment, a cruise on a superyacht full of rich people. After she witnesses a woman being thrown overboard, she fights against doubters to solve the mystery. This isn’t as much Agatha Christie as it is a paranoid thriller with her trying to outwit the expanding group of suspects. The best thing about the film is the beautiful boat where it all takes place. Otherwise, it’s a rather uninteresting puzzle with unlikely developments that strain credibility. Knightly is adequate, but Simon Stone’s direction doesn’t manage any real tension until near the end and even then, it’s not much of a payoff.
