Wealthy, elegant Brit Luke Evans invites them for a weekend on his yacht, which ends up, naturally, in murder. And they're the suspects!
Now the couple are on the run and forced up to their game, including their wardrobe. Since he's a cop and she's a mystery book buff, it's up to them to clear the names and find the real murderer.
Enjoy the trailer, set to Taylor Swift's "Look What You Made Me Do."
