Sarah saw something but she's not sure what it means.

There's something wrong with the couple living in the building across the street. The husband doesn't seem like a nice man. His wife always looks terrified.

Sarah can tell other people sense something is wrong too, but they won't speak up. They're afraid. Afraid of what, she doesn't know. She's made it her mission to find out.

Sometimes, it's best not to look too closely at other people's lives. You never know what you might find. And what it might cost you.
