Just You and I Tonight

When Sarah Wood is told she has to babysit on the night of her last party as a senior in highschool, she's not too happy. But when she gets to a beautiful house with windows for walls, miles away from society, what happens when a massive storm hits, and a stranger shows up at her door? Who is he? What does he want? He couldn't possibly have wandered there through the storm, uninjured. Where was he coming from? And when they hear a third voice, who is it that gets hurt?
