Ever have the feeling you're being watched?

Newlyweds Lina and Cain don't make it out to their property on gorgeous Lake Tarawera as often as they'd like, so when Cain suggests they rent the house out to vacationers, Lina reluctantly agrees. While the home has been in her family for generations, they could use the extra money. And at first, Lina is amazed at how quickly guests line up, and at how much they're willing to pay.

But both Lina and Cain have been keeping secrets, secrets that won't be put off by fresh paint or a new alarm system. And someone has been watching them--their mundane tasks, their intimate moments. When a visit takes a deadly turn, Lina realizes someone out there knows something they shouldn't...and that welcoming strangers into your home is playing a dangerous game.
