Perfect Strangers (2004)

When Melanie goes home from the pub with the best looking bloke there, she is more than pleased with herself. After a night of revelry, she passes out on his boat and is sailed away to his "castle"--a rundown shack on a deserted island. Melanie’s passion for the man quickly subsides, however, and romance turns to rage, as she realises she has been kidnapped. Escape is Melanie’s only available option, but her suitor has other plans.
