Both seventeen. Both afraid. But both saying yes. It sounded like the perfect first date: canoeing across a chain of lakes, sandwiches and beer in the cooler. But teenagers Amelia and James discover something below the water's surface that changes their lives forever. It's got two stories. It's got a garden. And the front door is open. It's a house at the bottom of a lake. For the teens, there is only one rule: no questions. And yet, how could a place so spectacular come with no price tag? While the duo plays house beneath the waves, one reality remains: Just because a house is empty, doesn't mean nobody's home.
