It's 1980 in a small town named Ostton. Only the millionaires can afford one of the big mansions that form the town, so young people leave to come back years later when they have already made a fortune.

It was clear from a start that the town wasn't normal. People who don't know their neighbors, cover their windows and isolate in their own gigantic houses. Almost empty streets, only an ocasional butler going out to buy some food at the almost abandoned grocery store.

Grace Dawson has decided to change that. A normal work most teenagers had at the time. Babysitting. She started by watching her little brother when her parents were too busy, and it all went great. But now, it's her first day babysitting for another family. What could go wrong?
